It seems that Mariah Carey and Britney Spears are the latest two #1 female artists to be involved in a catfight. Apparently at the centre of this argument, is American football player Tom Brady. Mariah recently threw a graduation party for her cousin, and Tom was invited. It's been said the two were very cosy together, but now Britney has decided that he is the man for her and has issued him a front row ticket to one of her next concerts, and made sure he has a "backstage" pass. Wonder what Mariah thinks of that?!
