Britney Spears performed on Tuesday night at the House of Blues in San Diego in a 'surprise' concert (watch video below). 

Rumors hit the internet saying that a band by the name M+Ms was actually Spears planning to launch her comeback with a series of concerts, and it turned out to be true!

This marked Britney's first public performance in three years.  Spears' arrival at the San Diego venue was greeted by a horde of aggressive paparazzi and excited fans.

Wearing a brunette wig, a short top and skirt with tall boots, she performed five of her previous hits and barely addressed the crowd. Fans say she was obviously lip syncing, and her set included Baby One More Time (Remix), I'm A Slave For You, Breathe One Me, Do Something and Toxic.

"I think she worked the stage, her body looked great. So it was good to see her finally come back and prove us all wrong," a female fan told Los Angeles TV station KNBC.

Britney is reportedly recording her fifth album.
