So you though that Christina Aguilera was just a former Mickey Mouse club member turn pop singer/stripper, turn reality show judge, huh? Oh how wrong you are. I mean, you're right, she has had more metamorphosis over the years than Spider-Man, but she's also pretty good at impressions. Namely other female pop singers.
This warrants another reminder that not only can speak like Britney Spears at maximum ditziness, but she can sing like her too.
So, should a comet hit the Earth and ONLY kill female pop stars, but somehow leave Christina Aguilera unscathed -- it's all good.
