Anthem-flubbing Christina Aguilera has a bigger scandal on her hands now: She was arrested early this morning in West Hollywood on charges of public intoxication. Her boyfriend Matthew Rutler was also charged with driving under the influence, TMZ reports. Aguilera looked "extremely intoxicated" and was "unable to take care of herself," law enforcement sources say, but add that "If the driver had NOT been arrested for DUI, [Christina] would have never been in trouble." Aguilera's friends say they've been trying to get her into rehab for weeks. (More Christina Aguilera stories.)
