Ashton Kutcher cheated on Demi Moore? Again? The gossip website TheDirty claims to have proof that Ashton Kutcher cheated on wife Demi Moore with Sara Leal, a girl he met Saturday at the Hard Rock Hotel in San Diego. The affair alledgedly occurred the same weekend as the Hollywood couple's sixth wedding anniversary.

People.com posted a tweet that Demi Moore (@mrskutcher) had sent out, citing that it may be related to Kutcher's infidelity: When we are offended at any man's fault, turn to yourself & study your own failings. Then you will forget your anger.

The NY Post is reporting that Moore is calling it quits, ending her six year marriage with Kutcher due to his recent escapades. The Post also reports that Leal went into hiding after the news leaked and has hired a top Hollywood attorney. And Star Magazine claims they have been living separate lives for months now.

Here is the e-mail TheDirty got from a supposed friend of this Ms. Leal:

Nik, I'm going to be straight to the point. I'm a female who works at who happens to be friends with Sara Leal, probably not after this. I'm sick to my stomach over what happen last Friday night. Like most people on earth I worshiped Ashton Kutcher and Demi Moore until Ashton Kutcher f*cked my friend Sara Leal at 4:30AM technically Saturday morning in his room on the 12 floor at the Hardrock Hotel in San Diego. Ashton Kutcher told Sara Leal that him and Demi Moore are separated and the public doesn't know yet. Smooth line Ashton, she was going to f*ck you anyway. Nik if you want to verify any of this just call Sara Leal yourself or ask Deena Omari. Better yet subpoena Ashton's bodyguard who took her phone before she came into the room.

According to the Inquisitr, Leal is now looking for $250,000 to tell her story.

On the flipside, Ashton Kutcher seems to be avoiding any hints of trouble in paradise on his Twitter feed. He is currently tweeting about #football4good.

Kutcher and Moore are currently on opposide coasts of the country. Moore is in New York promoting her Lifetime TV anthology Five while Ashton is in L.A. where he recently attended the Promise Gala 2011.

The quote, by Greek philosopher Epictetus, was tweeted by Moore on Sept. 23.

Last year, a woman named Brittney Jones claimed she had had relations with the married Kutcher.

Kutcher and Moore married in 2005. Kutcher is currently the star of CBS hit series Two and  a Half Men and reportedly makes $700,000 per episode.
