Best we can figure, Wilmer Valderrama emits some sort of hypnotic musk that makes him irresistible to starlets (see Demi Lovato, Lindsay Lohan, Mandy Moore, Jennifer Love Hewitt, Ashlee Simpson, et al.). And it appears his pheromones have now overloaded the senses of another young beauty.

People mag spied the indiscreet actor cozying up to sometime Derek Jeter squeeze Minka Kelly in a private booth at Los Angeles hot spot Greystone Manor earlier this week.

An eyewitness says they "were all over each other. ... They were very flirty and dancing close. They even left with each other."

Adds a source to Us Weekly, "They were kissing and grinding."

This is the latest outing for the twosome. In late February, Wilmer, 32, and Minka, 31, turned up at Beacher's Madhouse in Hollywood, where they stuck close all night but kept the PDA to a minimum. They also reportedly spent a day at Disneyland.

"I wouldn't say they're boyfriend and girlfriend," an insider tells Us. "But he's started ignoring calls from some of his other girls."

Guess this means that Kelly's romance with New York Yankees star Jeter has once again hit the skids. The low-profile pair split last August after three years of quiet coupledom, although they sparked reconciliation rumors in January with a romantic trip to Paris.

According to People, Minka is currently "doing fine" and has returned to Los Angeles after an extended stay in New York.

Wilmer, meanwhile, tells Perez Hilton that he had a perfectly good reason for his pre- and post-rehab romance with Lovato, who is a dozen years his junior.

"We were really just best friends, and to be honest I couldn't be more proud of her," he said. "She's a great human being. ... I was very proud to be there for her when she needed me and she was there for me a number of times, too."

So, what do you think: Is the erstwhile Fez an upgrade or a downgrade for Minka? Tell us in the comments.
