When Jeremy Renner celebrated her 40th birthday, celebrities came to celebrate.  Not everyone had a good night as it was discovered that singer Christina Aguilera passed out on the party! When Renner went up to his bedroom, he was surprised to see the singer on his bed and her boyfriend rubbing her back.  When he talked to her, she was slurring.  “Who comes to someone's birthday party that they don't know and gets in their bed? My parents were there!" She was a mess and acted like a fool, Tsk! Tsk! That was not good Aguilera…you shouldn’t have been drinking in the first place.  Everybody knows that if you can’t handle liquor, don’t drink at all.
