Britney back on stage

Britney Spears took to the stage today in California, in what is believed to be her first public concert appearance in nearly three years.

Starting the five-song set at San Diego's House of Blues with her classic 'Baby One More Time', Spears was back in top form. The boots-wearing one-time teen pop queen appeared on stage in a pink bra top and a short white skirt with her belly ring out.
