While guesting alongside Jon Cryer on "Watch What Happens Live," "The Longest Ride" star, Scott Eastwood, let slip a mightily juicy tidbit of gossip.

Eastwood countered Cryer's comments on the awkward-factor of him and "Two and a Half Men" co-star Ashton Kutcher being romantically involved with Demi Moore (Cryer dated her in 80s) by saying, "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."

"I think it was the catalyst that broke him and Demi up," Eastwood continued. Host Andy Cohen asked if it was the infamous girl at the San Diego Hard Rock Hotel (there were reports that Kutcher cheated on Moore while partying there in 2011), to which Eastwood replied, "Yeah, it was her and her friends. My buddy and I dated those two girls. Mmmhmm, yeah, scandal."
