We now know the identity of "this girl."

In the latest issue of Star Magazine, the tabloid cover touts an affair between Ashton Kutcher and a random 21-year old who claims she slept with the actor in the house he shares with wife Demi Moore. She's been identified as Brittney Jones.
In the article, Jones confirms that she met Kutcher at a bowling alley, exchanged numbers with him and started to receive texts asking if she was busy.

"I did all the suggesting in the texts, it was like he was paranoid and didn't want to text anything that would get him in trouble," Brittney said. "I asked him if he wanted to meet, that's how we made the plans."

Those plans, allegedly, included a sexual romp on a couch in Kutcher and Moore's living room. But Jones at least had nothing but positive things to say about the experience:

"He's a great lover. Very considerate and sweet. And it was very special to me."

Makes perfect sense. The guy is supposed to have a very big penis.

This is the second time Star has accused Kutcher of cheating on Demi. He threatened legal action after the initial story and his lawyer spoke out after this issue hit newsstands.
