Get A Grip On Yourself - Jen's New Man ID'd!

We've been wondering about the identity of the mystery man Jennifer Aniston took home from Courteney Cox' post-Oscar party for over a week now - but the wait seems to be over!

This week's OK! Magazine identifies Jen's mysterious beau as Brian Bouma, a Vancouver-based key grip. Jen and Brian met on the set of Traveling, where Brian was in charge of moving heavy equipment around.

As for how Bouma managed to stay so cool in the presence of the paps, according to a source who spoke to OK!, it turns out that the guy's got some previous experience - "He's actually quite a ladies' man," the mag's source says. "He's dated actresses before. But he's keeping in touch with Jen - he's even planning a visit to Miami soon!"

Bouma, of course, is keeping his lips locked about his celebrity ladyfriend, brushing off OK!'s questions about his relationship to Jen with a brusque "I don't want to talk about that." Sounds like a confirmation to us!
