Ashton Kutcher is being asked to pay a six-figure sum to a blonde who claims she had sex with him on the same day he and wife Demi Moore celebrated their sixth wedding anniversary.

Sara Leal, 23, is preparing to tell the story of how she hooked up with “Two and a Half Men” star Kutcher, 33, at the Hard Rock Hotel in San Diego last Friday, following a boozy night with his guy friends, according to a report on thedirty.com.

Now Leal has met with Beverly Hills lawyer Keith Davidson, who represented former Betty Ford worker Dawn Holland after she complained Lindsay Lohan attacked her. Holland dropped her claim after settling with Lohan’s camp, reportedly for $25,000.

A source said, “Sara is talking to multiple media outlets for a deal. She wants $250,000, but the offers haven’t been as high. What she really wants is to get a payoff from Ashton. She has reached out to Ashton’s team.”

Whether Kutcher, 33, can rescue things with Moore, 48, is not known. The pair spent their anniversary on Sept. 24 apart and — both prolific tweeters — have remained silent.

Kutcher’s lawyer Marty Singer, and a manager who reps both stars, refused to comment.

Kutcher was in San Diego and partied with actor Danny Masterson at Fluxx nightclub on Friday, where Leal is alleging he had sex with her at his hotel, according to thedirty.com.

Moore, at a New York event on Monday, appeared thin and gaunt and refused to do interviews. She and Kutcher were last pictured together on her Twitter feed in July. But recently Moore’s posts have been darker. On Sept. 23, she quoted a Greek philosopher, writing, “When we are offended at any man’s fault, turn to yourself & study your own failings. Then you will forget your anger.” On Monday she posted a picture of her face with her eyes closed, and the words, “I see through you.”

With Kutcher wearing a full pig’s head mask and kabbalah-practicing Moore wearing pig ears, they rolled into Meatpacking District club SL at about 2 a.m. Sunday morning and hit the dance floor.

Ashton kept the mask on, said one observer, “assumedly so no one bothered him while he danced — not that he didn’t draw enough attention by wearing a pink, oversized stuffed mask.” The couple and Moore’s daughter, Rumer Willis, also went over to Avenue, and sat near Kings of Leon rocker Jared Followill.

And while newly single Ashley Greene maintains she’s “just friends” with Followill, she came alone to Avenue at 3 a.m. to meet up with him. The pair were “very affectionate,” said a witness.

The 48-year-old actress kept embracing Colin Owens on the set of her 32-year-old spouse’s new movie ‘No Strings Attached’ because they looked so alike from behind.

Colin – who also worked alongside Natalie Portman in the romantic comedy – said: “More than once on the set Demi has come up behind me and you know, hugged me thinking I was Ashton because we were dressed the same.”

However, Colin revealed Demi always realised her mistake and never tried to kiss him, and insisted he would never have reciprocated her gestures.

Asked by website HollywoodLife if he was tempted to make a move back, Colin added: “No! She’s a great woman. She’s a friend . so, no.”

Ashton, meanwhile – who wed Demi in 2005 – admits their marriage works because they are both actors.

Asked if his wife ever got jealous over his sex scenes with Natalie, he said: “No, the beauty of my relationship is that we are both actors so we both understand what we have to do at work and what that entails so it’s a good thing being married to an actress!”

The handsome star recently admitted he is always working hard at his marriage – and likes to use social networking websites to send affectionate messages to his spouse.

He said: “Sending sweet nothings on twitter or Facebook is fun. In some ways, it’s no different than sending flowers to the office: You are declaring your love for everyone to see. Who doesn’t like to be publicly adored?”
