Britney Spears performed for a whopping 15 minutes last night at the House of Blues in San Diego.

For those who care, here's AP's breakdown:

* She wore "nothing more than knee-high go-go boots with a short white skirt and a sparkly pink bra top that showed off her belly button ring — and no evidence of the weight gain that landed her on celebrity tabloid covers last year. A long brown wig completed the outfit, covering the head she shaved in February."
