Lots of drama with Christina Aguilera this morning, after she and her boyfriend Matt Rutler were arrested in West Hollywood, about 2:45AM.   Here's what happened:  Rutler was busted for DUI, she was booked for public intoxication.  TMZ is reporting that although she was arrested, booked, fingerprinted, put in a cell and monitored - she was "not involved in any criminal activity", and has now been released from custody - once they determined that she could safely take care of herself.  Her boyfriend is still in the pokey, she just returned home.
