Ashton Kutcher wants hot tub women!

Ashton Kutcher is a bad husband.

According to the new issue of Us Weekly-magazine, the actor who’s married to Demi Moore spent the evening of his sixth wedding anniversay at the San Diego Hard Rock Hotel which culminated in a sexual encounter in a hot tub with local blonde Sara Leal in his $2,500-a-night hotel suite.

Moore, 48, was elsewhere in the U.S. promoting her directorial work for the Lifetime short film project 5.

“He said none of the girls were ‘hot-tub worthy,’” a source said.

“Ashton told them he was separated from Demi.

“Within five minutes, they were all naked in the hot tub, making out!”

Meanwhile, sources close to Demi say she’s “struggling. She’s been alone a lot lately.”
