Happy Birthday, Jennifer Love Hewitt

Jennifer Love Hewitt

I really should do something about all of these pictures I have of this lovely young lady:

'Ghost Whisperer' star Jennifer Love Hewitt turned 31 this weekend -- apparently, the actress also turned into Lady Gaga. Hewitt and some of her friends were caught on camera in outlandish outfits for Hewitt's '80s-themed birthday party, but their intensely-gelled hair bows evoked nothing so much as the 'Bad Romance' singer-fashionista.

So far, no photographs have emerged of Hewitt's boyfriend Jamie Kennedy on the big day, but we're willing to bet he stayed true to character by going all out. Hewitt told PEOPLE just before Valentine's Day that Kennedy knows how to treat a lady.

"He's done a bunch of romantic things just because that's who he is," she said. "It's hard to pick just one."

Here's to some happiness for the lady on her birthday.
