Christina Aguilera was detained last night on suspicion of public intoxication after the driver of the car she was in was arrested for driving under the influence, according to a spokesperson for the Los Angeles County sheriff’s department. The driver, Aguilera’s boyfriend, Matthew Rutler, was booked for DUI at around 2:45 a.m. after being stopped at the 1100 block of Clark Street in West Hollywood. According to a statement from the sheriff’s department, “Since she was not able to care for her safety and no one was available to ensure her safety, Aguilera was taken into custody. Sheriff’s Department officials stressed that she was not involved in any criminal activity and will be released when she can safely care for herself.”
