Blake Lively Almost Landed This Cult-Classic Movie Role

'That is so fetch!'

"On Wednesdays, we wear pink," said Karen Smith, played by... Blake Lively?

It seems that was almost the case, as the Gossip Girl alum was close to landing the role in 2004 hit film, Mean Girls.

For the unfamiliar, here's a quick rundown: The early-2000s cult classic, written by Tina Fey, follows teenage Cady Heron (Lindsay Lohan), a naive, unassuming but good-natured transfer student from another country who inadvertently befriends "the Plastics"—the popular clique of, well, mean girls—at her public high school in the suburbs of Illinois. As she navigates the lay of the land in her new turf, she quickly finds out how her shallow new girl group earned their nickname, ultimately deciding to steer clear of future drama associated with the crew.

The movie also stars Rachel McAdams as ringleader, the notorious Regina George, and Lacey Chabert as spoiled rich girl, Gretchen Wieners.

Amanda Seyfried, who ultimately got the part of Karen, recently chatted with Vanity Fair, recounting the elaborate process of being cast for what would become her feature film debut.

“I’d flown out to LA for the first time with my mother. It was very exciting,” she told the outlet of her audition. She was 17 years old at the time.

Seyfried noted that Lohan and Chabert  were already on board and in the audition room, adding that surprisingly, she actually had her heart set on playing Regina George, with another actress trying out for the part of Karen.

“Blake Lively was playing Karen, and then I was Regina,” she said.

Following the audition process, Seyfried was shocked to learn she had landed a different slot than she vied for, as producers told her she’d be perfect for the role that Lively had read the part of.

After a myriad of casting switch-ups—some of which included McAdams contending for Cady, Lohan originally being suggested for Regina, and even Ashley Tisdale trying out for Gretchen at one point—filmmakers eventually landed on the actresses for the roles that fans ended up seeing in the finished flick.

“When we did the testing, I found that when Rachel came into the room Lindsay got quite nervous,” director Mark Waters previously divulged. “She was a little intimidated by her as Rachel was older, had worked a lot, and was a very serious actress. It did something to Lindsay I liked, so in the testing process head to head Rachel was the better choice.”

As far as we know, it seems everything fell into place as it was meant in Seyfried's eyes. “I don’t know how we created our dynamic as the Plastics, we all came from such different places. We were different ages,” she told the publication. “I remember the feeling of everyone really wanting to be there and really appreciating the ingenious of the script.”

“There was just a vibe,” she added. “They cast it right. We were all pretty cool people."

Nearly 20 years later, it's hard to imagine the movie any other way!
