Sara Leal, Ashton Kutcher and Demi Moore: What’s going on?

Just because Aston Kutcher has taken over for Charlie Sheen on “Two and a Half Men,” doesn’t mean he has to act like the infamous Hollywood bad boy.

It looks as though Kutcher, 33,  has picked up a page from Sheen’s bad-behavior playbook as allegations are flying today that the star cheated on wife Demi Moore — on the weekend of their sixth wedding anniversary. 

Sara Leal, a 23-year-old blond, has come forward with the bombshell claim that she had sex with Kutcher after they met at a San Diego club last Friday.  Kutcher was there celebrating with his “That 70s Show” co-star Danny Masterson for his birthday — the same weekend of his anniversary with Moore, according to Radar Online. Leal has gone into hiding, but not before lawyering up with a Hollywood attorney. TheDirty.com reports that Ashton told Leal that he and his wife were “separated, but the public just didn’t know yet.”

Much as been made of the fact that not only was Kutcher partying on their anniversary, but he and Moore were even on different coasts — Moore was in New York City working on the upcoming film “Magic Mike.”

There’s no official word from the couple’s publicists but Moore sent this cryptic Tweet on Sept. 23, by the Greek philosopher Epictetus: “When we are offended at any man’s fault, turn to yourself & study your own failings. Then you will forget your anger.”
