Christina Aguilera – Stars at Prom

In the prom coup of the century, Christina Aguilera had a wicked threesome with the geekiest guy in school, proving she was 'Dirrty' even back then.

Thanks for making duck-lips before they were cool, ladies.

Unfortunately for X-Tina, when she went to her boyfriend's senior prom way back in 1999, the other girls snubbed her all night. And when her hit single 'Genie in a Bottle' was played, everyone refused to dance.

Ouch. That's enough to make a girl wish for a little pig's blood to throw around.
