As we all know, there’s only room for one gormless-looking, vaguely past-it American blonde dimwit in the world of pop at a time.

And, as we speak, that gormless-looking, vaguely past-it American blonde dimwit happens to be Britney Spears, with her shiny hair and lovely big desperate-looking eyes. That’s not great news for Christina Aguilera, who also happens to be a gormless-looking, vaguely past-it American blonde dimwit. She’s got a new album coming out soon! Grr!

But Christina Aguilera is nothing if not resourceful, and so to promote her new video Keeps Gettin’ Better she’s decided to become a gormless-looking, vaguely past-it American purple-haired dimwit instead. That’s fiendishly clever of Christina Aguilera – so fiendishly clever that it almost made us forget that the song is dreadful. Almost. Video after the jump.
