Mila Kunis and Ashton Kutcher's PDA at 'Oz' premiere party

mila-kunis-ashton-kutcher-PDA-party.jpg Mila Kunis walked the yellow brick road alone at the premiere of "Oz the Great and Powerful" on Feb. 13, clad in an off-white Dolce & Gabbana dress and silver Christian Louboutin heels. But she wasn't flying solo later.

Partygoers from the premiere afterparty tell US Weekly that Kunis and Ashton Kutcher arrived at the party together, holding hands. Kutcher was in a baseball cap and sweatshirt, while Kunis had put a bomber jacket on over her premiere dress.

"Mila ended up sitting on Ashton's lap," says a partygoer. At a little after midnight, they were seen kissing and then Kutcher "wrapped her in his arms" as she leaned her head on his shoulder.

The two have always played very coy about their relationship. Kunis recently hinted at the coupling on "The Ellen DeGeneres Show."
