Ashton Kutcher has had quite the week -- he's had to dodge allegations that he cheated on his wife Demi Moore with a 23-year-old blonde.

Sara Leal claims she hooked up with the Two and a Half Men star at Fluxx in San Diego last weekend, and now pictures have surfaced proving the star was, indeed, at the club. Ironically, it happened to be the same weekend of his sixth wedding anniversary to Demi.

A source inside the club tells X17online exclusively:

    "Ashton was having a blast in the VIP section drinking with his buddies. Then his group went to the dance floor and he was checking out the girls while they danced. Out loud he said, 'None of these girls are hot tub-worthy.' He didn't seem to care who was listening."

Ashton was seeing partying with his former That 70's Show co-star Danny Masterson and Danny's brother Christopher.

Earlier today, Ashton and Demi spent the morning together at the Kabbalah Centre in Los Angeles. Despite the affair allegations, both stars continue to wear their wedding rings.
