Andy Cohen got a lot more than he was bargaining for on last night's episode of Watch What Happens Live. The host sat down with Two and a Half Men star Jon Cryer and Scott Eastwood -- and the world turned small when Andy realized Jon had slept with Demi Moore, who was once married to his Men co-star Ashton Kutcher, who just so happened to have slept with Eastwood's ex girlfriend while they were dating.

In the sit-down, Cohen brought up the new reveal that decades ago Cryer had had a fling with Moore and asked the sitcom star if it had been awkward on set with Kutcher. The Pretty in Pink star said that things were cool with the two -- despite their common … eh hem … bond. However, things took a strange turn when Eastwood interjected that his girlfriend back in the day two-timed him with Kutcher.

"If it makes you feel any better, [Ashton Kutcher] did sleep with one of my ex girlfriends -- but she was my current girlfriend at the time," said Eastwood.

Four years ago, the Dude Where's My Car star's life and marriage blew up when he allegedly had a fling with Sara Leal (the one who Eastwood claims to have been dating at the time) at the Hard Rock Hotel in San Diego on September 24, 2011.

After the news broke, Leal came forward and told FOX411.com, "I don’t watch television and I read very few magazines. It never crossed my mind that he was married. But then he said he was separated, which still doesn’t make things okay, but I wasn’t thinking clearly."

Looks like Demi wasn't the only one who got hurt!
