Christina Aguilera's Bathroom Lovin'

Christina Aguilera has been quite the party girl since her split with husband Jordan Bratman.

A source has confirmed to Us Weekly that the singer and her new 25-year-old beau, Matthew Rutler had sex in a bathroom at a recent family gathering.

"Her friends are fed up," the source says of Aguilera's recent antics, which included a New Year's Eve blowout fight with her mom and a booze-filled night of crying at L.A. club The Dime in January. "Nobody can get through to her. They think she's trashy. And her ego is out of control."

Another source added:

"She's really spiraling," says the source. "I would be shocked if she's not in rehab in the next month or two."
