We love playing the twin game with lookalike stars from today, but what about the modern A-listers who look exactly like icons from yesteryear? From old Hollywood glamazons to current "it" stars, here are the mind-blowing side-by-sides of some of our favorite celebs and their counterparts from another era.

From their big eyes to their full cheeks, it's hard to tell the difference between a young Helen Mirren and Jennifer Lawrence.

Both in looks and personas, Sofia Vergara is Sophia Loren's modern day counterpart. Given their sultry looks, it's no surprise the two women became sexy screen sirens.

If they weren't decades apart in age, we'd be pretty sure that Lauren Bacall and Karlie Kloss, with their heart-shaped face and deep set eyes, were long lost twins.

Liv Tyler possesses the same delicately fair skin, dark hair, and green eyes that made Ava Gardner one of the biggest film stars in the '40s and '50s.

If you told us model Jourdan Dunn was the '80s singer Sade's clone, we'd believe you. Their almond-shaped eyes are almost identical.

People have often compared model Kendall Jenner to the '70s actress Ali MacGraw, and it's clear why. It's not just their long dark hair though—they give the same stare to the camera, too.

A pre-mustache Tom Selleck reminds us a lot of The Vampire Diaries star Ian Somerhalder. Maybe Ian should give a 'stache a go?

Both Audrey Hepburn and Lily Collins have the acting chops to back up their beauty. The two actresses also share many of the same petite facial features.

Another spot-on Audrey Hepburn lookalike is Rooney Mara. Between her cropped bangs, close-lipped smile, and bold eyebrows, it's no wonder why Mara is producing and starring in an upcoming biopic about the icon.

We think it's their oval faces and slender jawlines that make Brandy the spitting image of '60s actress Olga James.

She may have played Marilyn Monroe in My Week With Marilyn, but Michelle Williams more closely resembles French film star Brigitte Bardot, if you ask us.

It's his soft eyes that make the devilishly handsome George Clooney a dead ringer for legendary actor Clark Gable.

Shalom Harlow and Olivia Wilde share the same square-shaped face and almond eyes. And lucky for both of them, this combo seems to be the key to being photogenic.

No, you're not seeing double. Orange is the New Black star, Uzo Aduba, has the same million-watt smile that Gladys Knight was known for.

Not only are they both chart-topping singers, but Harry Styles takes after the legendary Rolling Stones singer in the looks department, too, sharing a similar nose and eyes.

A few years his junior, Joseph Gordon-Levitt is very reminiscent of the late Heath Ledger with their thin smiles and dark, deep eyes.

The resemblance between Helen Hunt and Leelee Sobieski is remarkable. We think it's their oval face shape and serious stare.

We're not sure if French actor Vincent Cassel has the dance moves of Fred Astaire, but between their strong chin and slight grin, we'd say he's a chip off the ole block.

Actresses Dorothy Dandridge and Maya Rudolph share the same oval-shaped face and subtle smile.

Friday Night Lights star, Minka Kelly, resembles actress Raquel Welch in many ways, including her wide set eyes and stunning smile.

The Queen of Pop and up-and-coming artist Sky Ferreira owe it to their short, sleek jawline for looking so similar. They have pretty similar brows, too.

Megan Fox may not share Jayne Mansfield's platinum blonde hair, but their brown eyes and full pouts make Megan nearly identical to the late film star.

It isn't just her success on the catwalk that has the fashion world buzzing that Bella Hadid is the next Carla Bruni—her high cheekbones make her a dead ringer for Bruni back in the '90s, too.

In every other way, Queen Latifah is truly unique, but when it comes to her looks, the singer and actress has a striking resemblance to novelist and folklorist Zora Neale Hurston.

Between their coiffed hair, thick eyebrows, and matching smirks, Marlon Brando and Dave Franco look like they could be related. Their good looks and talent made them sought-after leading men in Hollywood.

The '30s film star, Hedy Lamarr, was glamorized for her fair skin and dark hair throughout her career. Almost 60 years later, Rose McGowan launched her film career with oddly reminiscent characteristics of the late actress.

We're still holding out hope that Debra Messing will get to play Lucille Ball one day. It's not just their fiery red hair—their personalities seem similar, too.

Christina Aguilera and '40s icon Ginger Rogers share more similarities than just being blonde bombshells. They also both made it in Hollywood as singers.

Sure, Mark Ruffalo and Burt Reynolds are both immensely talented and notoriously laid-back actors, but they also share the same jawline.

We know Gwen Stefani will be elated by this matchup. After all, the singer first started dying her hair platinum blonde to emulate the screen star. Their famous red pouts are just the cherry on top.

Empire actress Taraji P. Henson bears an uncanny resemblance to '60s Motown singer, Tammi Terrell. It's like looking in a mirror, well, for Taraji P. Henson that is.

This is our official plea for Jessica Paré to play Jane Birkin on screen. One was a '70s fashion icon and the other played a '70s housewife on Mad Men, but both are essentially carbon copies of one another.

Both Cara Delevingne and Stevie Nicks exude a rocker chic energy that's undeniable, but the two also share the same round button nose.

Are we seeing double? We think it's their brown eyes that make Kate Mara looks just like The Graduate star, Katharine Ross.

Three Sharon Tate films premiered in 2019, but not one cast Sharon's present day doppelgänger (at least, according to us), Rose Byrne.

Joan Crawford was famous for her high arching brows, which she popularized in the '40s. We think that the same characteristic on Kate Winslet is what makes the two actresses look so much alike.

It's normally Amy Adams that the public confuses Isla Fisher with, but looking back a few decades we can't stop seeing the likeness between Isla and Bye Bye Birdie actress Ann Margret.

Reese Witherspoon looks nearly identical to The Last Picture Show starlet. Besides sharing blonde side parts and piercing blue eyes, both women were casted in their breakout roles in their early 20s.

Both Joan Fontaine and Chloë Grace Moretz started acting as children, but it's their high cheekbones and sharp chins that give them even more in common.

Both Paul Newman and Ansel Elgort have worked on an impressive number of films, and both actors share the same full lips and jawline that gives them their movie star looks.

Between Sandra Dee and Carey Mulligan's pale complexions, full cheeks, and almond eyes, the two actresses could not be more alike—despite working in Hollywood decades apart from one another.

From their floppy blonde hair to their chiseled jawline, it's easy to see why Brad Pitt and Robert Redford were the heartthrobs of their respective generations.

It's no surprise that Leonard Whiting and Zac Efron were both teen heartthrobs in their heyday. From their piercing blue eyes to their chiseled jaws, Efron is the spitting image of the Romeo and Juliet actor.

The dark hair, bold accessories, and perfect eyeliner make these two look one and the same. It might not be a coincidence either: Before Del Rey coined her now-famous stage name and was just known as Lizzy Grant, the singer admitted to HuffPost that Elvis's songs became the soundtrack of her life early on.

While Lindsay Lohan normally sports red hair, she was temporarily brunette in 2006, which drew attention to her violet-green eyes making her a dead ringer for Elizabeth Taylor. And we're not the only ones who think so—Lohan portrayed Taylor in the biopic Liz and Dick.

Though Scott Eastwood's looks have largely been compared to those of his famous father's, Clint Eastwood, we can't help but see a resemblance between him and Rebel Without a Cause actor James Dean. It seems like Scott has even mastered Dean's famous eye squint.

While Jeff Bridges and Liam Hemsworth share a laid-back attitude, they also closely resemble one another. A young, clean-cut Bridges is the spitting image of the youngest Hemsworth brother, right down to that soft smile.

Game of Thrones actress Natalie Dormer's looks are reminiscent of Old Hollywood star Gene Tierney. The actresses both share green upturned eyes and a square-shaped face.

His deep set brown eyes, prominent nose, and strong eyebrows make Christian Bale a lookalike for a young James Brolin.

There's something about Alec Baldwin's almond-shaped eyes and strong chin that make him the carbon copy of Davy Crockett's Fess Parker. That, and the fact that they both have a terrific head of hair.

Besides the fact that both actresses have long golden red hair, Connie Britton's sparkling eyes are very similar to those of 1940s film star Rita Hayworth.

It isn't just her fair complexion or dark brown eyes and hair that make Anne Hathaway so closely resemble the Italian film star. It's also her oval-shaped face and full pout.

There are a lot of characteristics that make Michael Fassbender the doppelgänger of The Sound of Music star. But their strong build and prominent jawline are just a couple of examples.

Despite their different hair colors, everything from Katherine Heigl's round face and dark eyes to her button nose are shared by Judy Garland.

From their heart-shaped faces to their arched brows, actresses Jane Fonda and Alyssa Milano may have broken into the business in different decades, but they could play sisters.

With all similarities between actress Octavia Spencer and singer Dinah Washington's facial features aside, it's their expressive eyes that have us seeing double.

With golden blonde hair, a square-shaped chin, and a button nose, director Greta Gerwig is a dead ringer for Old Hollywood film star Lana Turner.

Michelle Pfeiffer looks very similar to Janet Leigh. Perhaps it's their small and slender noses or their square-shaped faces. Regardless, it's making us want a reboot of Psycho with Pfeiffer as Marion stat.

With their similarly shaped noses, upturned eyes, and diamond faces, there's no denying the resemblance between Ruby Dee and the This Is Us actress.

For all we know, Florence Pugh could be related to It Happened One Night star Claudette Colbert. Between their square faces, full cheekbones, and bright eyes, it wouldn't be surprising.

Not only are Diahann Carroll and Kerry Washington both talented actresses, the two women look a lot alike with their wide set eyes and oval-shaped faces.

It's clear that musical talent isn't the only thing Lena Horne and Alicia Keys have in common. Between their slender jaws, diamond faces, and button noses, who couldn't see the resemblance?

Grace Kelly's delicate features and fair complexion were only a couple of the things that made her appear so elegant on the screen. Flash forward more than 60 years later and you'll find her Hollywood dopplegangër, Rosamund Pike, with the same characteristics.

We can't get over how similar Jason Segel looks to 1950s actor Lee Cobb. From their square jaw to their hooded eyes, it's hard not to see the resemblance.

Between their round faces, high cheekbones, and hooded eyes, Gigi Hadid is the spitting image of Old Hollywood star Greta Garbo. In 1950, The Guinness Book of World Records dubbed Garbo the "Most Beautiful Woman that Ever Lived," and Hadid just so happens to be a big name model herself.

Seeing how similar Eartha Kitt and Zendaya look to one another is goosebump-inducing. Zendaya's square face, almond-shaped eyes, and prominent brow make her a dead ringer for the famous singer.

In this case, good looks run in the family. Dakota Johnson is the granddaughter of actress Tippi Hedren, and it's not hard to see the resemblance.

It isn't just Rachel Weisz's dark brunette hair, oval face, or full pout that reminds us of Hedy Lamarr. The actresses have almost identical prominent brow arches, which makes them almost indistinguishable.

You can't miss the ears on either Bing Crosby or Daniel Craig. Paired with their blue eyes and oval-shaped faces, there's almost no telling them apart.

Kelly Rowland may not be the Queen of Disco, but she does look strikingly similar to her. Donna Summer and Rowland both share oval faces, wide set eyes, and killer voices.

If this isn't a reason for Taylor Swift to try a pixie cut, what is? The singer could easily be mistaken for '60s actress, Mia Farrow, with their long slender noses, wide set eyes, and heart-shaped faces.

Actress Essence Atkins is almost identical to Diana Ross, with a diamond-shaped face, high cheekbones, and large round eyes.

It's not hard to see the resemblance between Elvis Presley and Justin Bieber, with their oval faces, strong jaws, and deep set eyes. Perhaps that's why they were both Hollywood heartthrobs.

While Viola Davis is known for taking on transformative roles, she wouldn't have to try too hard to play Nina Simone. The Oscar-winning actress looks a lot like the late singer, with similar noses, wide set eyes, and round faces.
