There's always some shocking news to learn on "Watch What Happens Live!" Scott Eastwood dropped by the usually candid and straightforward show to have a talk with the show's host Andy Cohen last Thursday night, along with former "Two and a Half Men" actor Jon Cryer, where Scott dropped a shocking revelation that caused Andy to grab a shotski.

In the segment where they interact with viewers via phone or social media, one viewer called to ask Jon a question about having previously dated actor Ashton Kutcher's ex-wife, Demi Moore, back in the 80s, when Scott immediately cut in the conversation to reveal his own bombshell.

Scott said, "If it makes you feel any better, he did sleep with one of my ex-girlfriends," to which Jon laughingly replied, "Great!"

Scott shared that the ex-girlfriend he's referring to was his girlfriend at the time, which caused Andy to chime in, in disbelief. Bewildered, he asked Clint Eastwood's son if Ashton, now Mila Kunis' husband, slept with his girlfriend while they were still together.

The star of the upcoming film "The Longest Ride," said "Yeah," and shared that it probably was "the catalyst that broke..." before Andy butt in and said, "broke you up?"

But Scott said no and said that it was maybe the catalyst that broke Ashton and Demi.

Ashton and Demi called it quits in November of 2011 after being married for six years. They finally got divorced in November of 2013.
