Ashton Kutcher's ex-mistress Sara Leal doesn't believe the actor's intimate sightings of PDF with Mila Kunis are signs of change.

The woman who Kutcher infamously cheated on ex-wife Demi Moore with is warning all who wish to be more than 'friends with benefits' with Kutcher to get out while you still can. 

"Once a cheater, always a cheater," Leal recently told The Sun. "If I were Mila I'd be careful, he doesn't have the best track record." She also added, "if I was dating a guy that had cheated on his wife I would be a little suspicious," she added. "It would probably make me extra crazy and extra insecure. I'd definitely keep an eye out."

In fact, Leal has suggested Ashton could already be doing the dirty deed behind Kunis' back, according to an article on Hollywood Life. "Apparently, the girl was at Ashton's house in L.A., and obviously someone was with him, but he didn't know he was in the picture. It was creepy. It could just be an innocent picture, but I think it's also possible he's not dating Mila exclusively," Leal said.

Leal, who admitted she slept with Kutcher in a San Diego hotel room in September 2011 on the actor's six-year anniversary to Moore, believed Ashton had no regrets the night after their affair. She also admitted to sleeping with the "Two and a Half Men" star on another occasion, with the actor requesting she bring a female friend, as well. 

Kutcher, who is set to star as Steve Jobs in the aptly named biopic "jOBS," has not spoke on Leal's comments, but recently admitted in an interview with Esquire that some of his movies "f***ing suck donkey." At least he's honest about some things, right?

Can Ashton repair his image? Is he doomed to cheat again? Let us know how you feel!
