Britney Spears Takes The Stage In Vegas And San Francisco

Britney Spears performed two shows this weekend to promote her new album Femme Fatale. The first show, held at the Palms Casino Resort in Las Vegas on Friday night, was technically a “secret” show which Spears tweeted about at the last minute on Friday, telling her fans “You’re all invited. Be there or be square bitch!” She also performed in San Francisco on Sunday. The Sunday show was sponsored by Good Morning America and part of it (the one with the least amount of crotch shots, we assume) will be broadcast on the morning show on Tuesday. Check out our gallery below for photos of her San Francisco show, and her live performance of “Hold It Against Me” after the jump.
