Wilmer Valderrama is now with Demi Lovato

Wilmer Valderrama has somehow slept with most of young Hollywood. He allegedly popped Mandy Moore’s cherry and then went on to Lindsay Lohan when she turned 18. Now that he’s older. He’s settled down. Ha, just kidding. No. These days he’s still flipping through Mickey Mouse’s yearbook and is now nailing Demi Lovato who recently checked into rehab. Lovato’s rep had no comment while Wilmer’s rep denied the relationship.

Following a breakup with Joe Jonas, Demi Lovato clung to an older actor, Wilmer Valderrama. Before the Disney star entered a facility for “emotional and physical” issues, sources said Lovato, 18, introduced pals to the “That ’70s Show” star as her boyfriend. Valderrama, 30, first connected with Lovato when they filmed a public-service spot together in Chile for earthquake relief in March, around the time she announced her relationship with Jonas. “The two started seeing each other in May right after her breakup with Jonas,” a source on the tour said. “She would show us pictures of them together.”

How does he do it? He must have a large collection of knives.
