It's Britney Bitch!!!! While Britney Spears was on stage at Radio City Music Hall she broke into laughter after a fan yelled "who is it." The reason why it's so funny is because he yelled that right before she uttered the famous opening line of her song 'Gimme More'....You know the line....'IT'S BRITNEY BITCH'
Her reaction is sooooo AMAZING!
Just watch!
