Britney’s back! I thought I was transported to a Beatles concert when I exited the backstage area into the arena. I’ve never heard so many screaming girls in my life – they reacted to her every move. She played to a packed house at the Tacoma Dome last night on the first leg of her US tour in support of her seventh studio album, Femme Fatale. She’ll be off to Europe in September for 26 more dates.
