He may have been daydreaming about cheerleaders or riding crops, but Charlie Sheen was at least on his best behavior last week when he met the parents of his new girlfriend.

Brooke Mueller, the daughter of Palm Beach socialite Moira Fiore, has been stepping doing the nasty with Sheen for a few weeks now. The elder Fiore said she and husband John went to California last week to be introduced to Sheen, 40. Her recount of the events:

"I've never seen my daughter happier," Fiore said. "She told me they laugh morning, noon and night, and that she's never been more comfortable with someone. Charlie says he loves her personality and, of course, her looks. As a mother, if they're happy, I'm happy."

And as a naughty sex fiend, if her daugher's hot, Sheen is happy. Other reports state that the ex-husband of Denise Richards introduced Brooke to his parents, including West Wing president, Martin, on Mother's Day.
