Ashton Kutcher cheated on Demi Moore. With this.

Ashton Kutcher was first accused of cheating on his wife Demi Moore about 3 weeks ago, and so he went on twitter and said...

"I think Star magazine calling me a "cheater" qualifies as defamation of character. I hope my lawyer agrees."

And while we're on the topic of Star, cheating, and short messages from Ashton Kutcher, Star magazine has posted some text messages that Ashton Kutcher sent to a girl named Brittney Jones so they could plan when Demi would be out of the house and they could bang.

After their tryst--and for over a month after their initial meeting--they continued texting and, in one exchanged Brittney asked, "Whens the next time you're gonna have an empty house?" To which Ashton replied, "Not sure maybe the end of the month." Noting at the time he was "w/ my daughter."

His long term relationship with Moore, who is 15 years older that Ashton, has been one of the things he's most known for, so if that falls apart, it could really hurt his public perception, and forever change the way people don't see his movies.

(and yes that's Brittney in the picture. No tits? Big ass? Oh my heart is pounding through my chest right now, I think I'm in love!)
