A stag and gum-snapping Britney Spears showed off her new brunette look at the Baby Phat Fashion Show on Friday night.

Without new man Isaac or her two sons in tow, the women voted the “World’s Worst Dressed Celebrity,” headed backstage to check out Kimora Lee Simmon’s new line of fall fashions at New York’s Fashion Week-Fall 2007.

Britney seemed to enjoy herself,” an attendee dishes. “Except for some annoying girl that kept snapping pictures of her.”

Kimora Lee played Kanye West’s “Gold Digger” during the catwalk (perhaps in memory of Brit’s hubs K-Fed?), Brit playfully danced along.
