OMG! Mila Kunis, Modern Family's Sarah Hyland Look Like Twins!

With their expressive green eyes and matching chocolate tresses, Mila Kunis and Modern Family's Sarah Hyland had partygoers doing a double-take during a private Nylon and Armani Exchange dinner in Hollywood Thursday.

It's not the first time Hyland, 20, has been mistaken for the Black Swan actress, 27: she and boyfriend Matt Prokop dressed as Kunis and Ashton Kutcher's That '70s Show characters on Halloween!

"We love the show, and people say I look like Mila Kunis," Hyland told JSYK. "I've always wanted to be Jackie for Halloween, so we just did it."
