They haven't admitted it, but 'That '70s Show' co-stars Mila Kunis and Ashton Kutcher are clearly hooking up -- and there's now photographic evidence of this unfairly attractive couple sucking face in New York City's Central Park.

Apparently they don't care who sees them lock lips, but the two engaged in their makeout session only a stone's throw from the crib he once shared with ex-wife Demi Moore. She still lives there, but we're going to assume she wasn't near a window at the time to see what was going on since she didn't fling herself through the glass or anything.

As you'll recall, Moore melted down after splitting with Kutcher last year in the wake of his manparts falling into ladyparts that didn't belong to her. She later smoked who knows what and wound up in rehab "to address her issues" aka "her broken heart and embarrassment at being abandoned by her much-younger husband."

The Kutch has clearly moved on, and with someone closer to his own age. Sources report that he and Kunis, who was with Macaulay Culkin for several years before trading up, were holding hands in the Village, taking every opportunity to practice the mouth-to-mouth part of the Red Cross CPR training we're sure they just took.

But there is a bright side for Moore when it comes to all this PDA: Kutcher's lips may be on Kunis, but his eyes are on his iPhone.

Seriously? Come on. What app could possibly be more interesting than tangling tongues with the woman who voices Meg Griffin on 'Family Guy'?

Maybe Moore dodged a bullet. Just sayin'.
