Britney SpearsShe's baaackk!

Britney Spears kicked off her Femme Fatale tour at the Power Balance Pavilion in Sacremento, Calif. last night and from the looks of it, her first night back on stage was definitely a spectacle.

No guitar too small, no bikini top too glittery for the pop princess. She pranced around the stage and danced with scantily clad men, straddled a gigantic guitar and rode a motorcycle all while belting out some of her most famous tunes.

The sold out crowd was in for a real treat. The 29-year-old singer chatted with Entertainment Tonight last week and divulged just a little about what fans could expect.

"I'm really excited," she said. "I'm probably going to be extra nervous the day before but we've been working hard for two months now, and everything is coming together."
