Christina Aguilera has been arrested, just a few weeks into her dark period. The 30-year-old singer was busted with her boyfriend early this morning in Los Angeles. TMZ reports 25-year-old Matthew Rutler was taken in for driving under the influence and held on 30,000 bail; Aguilera was booked for public intoxication, which our source tells the website meant she was extremely intoxicated and unable to take care of herself. The star has since been released from custody she was finger printed and placed in a cell and will not be prosecuted for the misdemeanor, L.A. County Sheriffs spokesman Steve Whitmore tells TMZ.
