Kutcher ex warns Kunis to 'keep eye' on him

Ashton Kutcher's former fling Sara Leal expects him to cheat on his new girlfriend Mila Kunis.

The 22-year-old blonde - who claims to have slept with the 'Two and a Half Men' star in a hotel room on his and ex-wife Demi Moore's sixth wedding anniversary in 2011 - says the 'Ted' star shouldn't trust the 35-year-old actor and thinks the brunette beauty should "definitely keep an eye" on him.

She said: "Once a cheater, always a cheater. If I were Mila I'd be careful, he doesn't have the best track record. But she's obviously willing to take that risk.

"If I was dating a guy that had cheated on his wife I would be a little suspicious. It would probably make me extra crazy and extra insecure. I'd definitely keep an eye out. That would be a red flag in my eyes, if I was dating somebody that cheated on their wife.

"I would hate for Mila to have the same experience as Demi. I wouldn't wish that on anyone. I would just hope that she's secure, and she seems a really smart girl. Everyone's relationship is different so hopefully Ashton won't cheat on her.

"Hopefully he learned his lesson. I think the fact that they were child actors together and friends before they dated is obviously a good thing."

Sara insists she didn't know Ashton was married when they had their fling, but she is sorry for what happened and thinks Demi - who completed a stint in rehab for a reported eating disorder and addiction issues shortly after they split in December 2011 - coped with the situation "the best way she possibly could".

She added to The Sun newspaper: "I'm sorry about what happened. I'm sorry to Demi - that's a terrible situation and I'm sure it was really hard. It was never my intention, but that doesn't make it OK.

"I've been cheated on so I know how terrible that feels. I can't even imagine what it feels like to be cheated on by a husband and have it blow up in your face.

"My intention wasn't to go out and ruin a marriage. I think Demi handled it in the best way she possibly could."
