Jessica Simpson's Son Ace Turns 2! See All the Cute Party Pics

The terrific twos!

Jessica Simpson‘s son Ace Knute celebrated his birthday in style on Tuesday, channeling Harry Styles and living it up on a bouncy slide.

The toddler, who was born in June 2013, was all smiles on his special day with his mom, 34, and dad, Simpson’s husband Eric Johnson.

Ace was clad in an awesome Hawaiian-print shirt for his party, wearing matching leafy-printed swim trunks as he posed on the slide.

“2yrs OLD?!?! Can we live here forever?” wrote Simpson on Instagram. “I love you Ace Knute Johnson. Happy Birthday!”

In another photo, the adorable family poses happily as little Ace sips out of a fire hydrant mug. Missing from the sweet snap? Ace’s older sister Maxwell Drew, 3.

Later Tuesday evening, Simpson shared an image of Ace post-party, likening his disheveled curly blond hair to the One Direction crooner’s signature mane.

“Ace Knute channeling his inner Harry Styles on the way home from dinner tonight,” the star captioned the fun snapshot.

Last weekend, the actress and singer shared pictures of Johnson and their son, embracing for the camera.

The star couldn’t help but admit to being “obsessed” with her “boys.”
