Although they’ve shot down the rumors about any romance between them for the past few months, we’re going to go ahead and say it’s safe it assume that they’re getting it on, because Mila Kunis and her former That 70′s Show boyfriend Ashton Kutcher were caught sucking face in LA on Saturday.

Partygoers who attended an intimate get together in West Hollywood this weekend were met with an apparent long-lasting PDA show when the Jobs actor and Ted actress made out for what insiders say was a good chunk of the night.

The former Mr. Demi Moore first sparked rumors that he may be dating Kunis when the two shared a series of dates at the Los Angeles hotspot The Soho House.

“They were seated on a couch on the same side of the table and Mila was running her hands through Ashton’s hair,” a source told Us Weekly. “She had her elbow resting on his back and couldn’t stop playing with his hair and rubbing his shoulders. He leaned in and whispered to her and kissed her cheek.”

We love love love it when fictional couples become a reality! Now if only Gossling and McAdams would start getting it on again…
