A young woman is accusing Ashton Kutcher of cheating on Demi Moore, the same weekend as the couple celebrated their six year wedding anniversary, according to Radaronline.

The website claims the liaison happened last Friday in San Diego, California after a booze-fuelled night out.

The 23-year-old woman, identified as Sara Leal, has reportedly hired a high powered Hollywood attorney and has gone into hiding.

According to Radaronline, the information was received from “multiple friends of the woman.”

An unnamed source said: “She is due to meet with an attorney tonight (Tuesday). She is freaking out.”

Ashton Kutcher and Demi Moore wedding anniversary was on Saturday, September 24, one day after the alleged encounter happened.

“Ashton didn’t look like someone who was celebrating a wedding anniversary,” one club goer told RadarOnline.

Star magazine is working on an explosive new report claiming the marriage between Ashton Kutcher and Demi Moore is “officially over”

The scandal also comes as Star magazine, a sister publication of RadarOnline, is working on an explosive new report claiming the marriage between Ashton Kutcher, 33, and Demi Moore, 48, is “officially over”.

According to Star magazine: “Ashton and Demi have separated and the marriage is over.”

Ashton Kutcher‘s representatives have not responded so far.

A source close to Ashton Kutcher and Demi Moore reportedly told Star magazine:

 “The relationship ended because of Ashton’s serial cheating. It’s a painful time for Demi.”

In September 2010, Ashton Kutcher was rocked by another cheating scandal after Star reported that he had had a fling with a 21-year-old woman named Brittney Jones.

Brittney Jones told the Sun she had sex with Ashton Kutcher inside the Beverly Hills home he shares with Demi Moore.

The magazine also claimed that Ashton Kutcher was so worried that the alleged affair would be exposed that he made her delete their text messages, but Star reported that she didn’t remove all of them.

Brittney Jones told Star: “He looked over the texts and said he wanted me to delete all the messages from him.”

“He then told me he wanted me to delete the texts I had sent to him. He said they could hurt him.”

Despite the explosive report, Ashton Kutcher and Demi Moore brushed off the allegations with Ashton making sure to express just how he felt by taking his Twitter to make a statement.

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

“STAR magazine – you don’t get to stand behind <<freedom of the press>> when you are writing fiction.”

Ashton Kutcher’s representative also denied the story, while his wife of nearly five years came out in support of her husband.

“Excellent point my love!” and “No question!” Demi Moore wrote in response to Ashton Kutcher’s comments.
