Britney Spears hit the stage May 1, with what was believed to be her first public performance in nearly three years.
Wearing a short skirt, go-go boots, a pink top, and a brown wig, the 25-year-old mother of two raced through her greatest hits at the House Of Blues in San Diego, California.
The set lasted less than 15 minutes, reportedly irritating some concertgoers who paid upwards of $125 per ticket. Mounting the concert under heavy security, the club advertised the headliners as "The M & Ms."
Attendees didn't know Britney Spears was performing until an hour after the doors opened. Rumors of a Spears show had spread via the Internet and local radio stations.
The House Of Blues web site advertised two more Southern California concerts by "The M & Ms": one in Anaheim on May 2, and the other in West Hollywood on May 3.
