Britney Spears says she loves San Francisco. And if her performance at the Bill Graham Civic Auditorium for a taping of Good Morning America is any indication, it seems San Fran loves her right back! She belted out three hits from her upcoming album Femme Fatale — “Hold It Against Me”, “Till the World Ends” and “Big Daddy Bass,” wowing the crowd in her tight, sexy bodysuits. She also hit the stage on Friday in a surprise show in Las Vegas. GMA will air her performance on Tuesday (US time) to coincide with the release of her album.
