Andy Cohen has a brilliant strategy for getting celebs to talk on his gosippy show "Watch What Happens Live": He just plies his guests with alcohol. And as the alcohol flowed recently, with guests Jon Cryer and Clint Eastwood's son Scott Eastwood ("The Longest Ride"), so did the secrets.

Cryer told Cohen and Eastwood, 29,  that it was a little awkward to work with Ashton Kutcher, 37, on "Two and a Half Men" because he'd once dated Kutcher's then-wife Demi Moore in the 1980s. Then, in a bit of one-upmanship, Eastwood said Kutcher slept with his ex-girlfriend Sara Leal -- while he was still seeing her. And Eastwood speculated that was the tryst that broke up Kutcher's six-year marriage to Moore.

"If it makes you feel any better, he did sleep with one of my ex-girlfriends -- but she was my current girlfriend at the time," Eastwood said calmly. He added, "I think it was the catalyst that broke him and Demi up." Moore filed for divorce in December 2011, the same year of Kutcher's alleged infidelity.

Although Kutcher never admitted to the affair, Leal went on a media contrition tour.

"I don’t watch television and I read very few magazines," she told Fox News. "It never crossed my mind that he was married. But then he said he was separated, which still doesn’t make things OK, but I wasn’t thinking clearly." In a different interview with The Sun in 2013, Leal stated, "My intention wasn’t to go out and ruin a marriage. I think Demi handled it in the best way she possibly could."

Kutcher is now coupled with his former "That '70s Show" co-star Mila Kunis, who recently gave birth to their first child, daughter Wyatt Isabelle. Eastwood, meanwhile, is set to co-star in "The Suicide Squad."
