Scott Eastwood Drops An Ashton Kutcher Bomb! Says Ashton Cheated On Demi Moore With His Then-Girlfriend -- And That's What Led To The Couple's Divorce!

Who would think that in a room with Andy Cohen, the unassuming Scott Eastwood would be the one to stir up some drama!
On Thursday, The Longest Ride actor joined Jon Cryer on Cohen’s Watch What Happens Live and serendipitously shed light on a major celeb scandal from way back in 2011 — when Ashton Kutcher reportedly cheated on Demi Moore!

It started when a caller asked Cryer if working with Two And A Half Men co-star Kutcher was awkward due to the fact that they both dated Moore.
Eastwood then innocently lamented that Kutcher also hooked up with his ex-girlfriend WHILE they were dating! When Cohen probed him for more, Clint Eastwood‘s son explained he wasn’t bitter about the situation at all — but then dropped the bombshell:

“I think it was the catalyst that broke him and Demi up.”

Wait — what!?
The WWHL host knew he struck gossip gold when Eastwood explained that his ex was actually one of the two women that Kutcher reportedly cheated on Moore with in a hot tub!
The original report claimed that a married Kutcher spent his sixth wedding anniversary sans Moore at a party in San Diego that led to a sexual encounter with two women. This reportedly resulted in the couple’s famous split shortly after!
Wow! We hope Mila Kunis wasn’t watching Bravo during this confession story time!
