BRITNEY SPEARS' SURPRISE CONCERT

For the first time in three years, pop princess Britney Spears took to the stage at the House of Blues in San Diego to do what she does best: perform for her fans. Wearing knee-high go-go boots with a short white skirt and a sparkly pink bra top, she gave her fans a very brief concert - around 15 minutes in total - of her biggest hits like Baby One More Time before thanking the audience at the packed club and disappearing backstage.Though House of Blues had advertised that evening's band as The M&Ms, it was widely believed beforehand that this was actually a pseudonym, prompting a rush on tickets for the sold-out show.The M&Ms had two other concerts scheduled at House of Blues venues in Southern California - one in Anaheim on Wednesday and the other Thursday in West Hollywood - according to the club's Web site.Photo: WireImage
