Los Angeles ( CNN ) -- Pop singer and actress Christina Aguilera was detained early Tuesday `` to ensure her safety '' after her rumored boyfriend was arrested on suspicion of driving under the influence , authorities said . Aguilera , 30 , was a passenger in a car that was stopped about 2:45 a.m. ( 5:45 a.m . ET ) in West Hollywood , the Los Angeles County Sheriff 's Department said in a news release . `` The driver , Matthew Rutler , was determined to be driving while under the influence of alcohol and arrested , '' the release said . Aguilera was determined to be intoxicated , said Los Angeles County Sheriff 's spokesman Steve Whitmore . `` She was not capable of taking care of herself , '' he told reporters , but said she was `` very cooperative , not belligerent in any way . '' She was technically arrested on a public intoxication charge , Whitmore said , but `` there was never the intent to prosecute . '' Such actions are routine in such instances -- when a driver is arrested and a passenger is determined to be intoxicated . Since Aguilera was not able to care for herself `` and no one was available to ensure her safety , Aguilera was taken into custody , '' the statement said . The department `` stressed that she was not involved in any criminal activity . '' Aguilera will have a record of the misdemeanor arrest , Whitmore said , and was booked , fingerprinted , put in a jail cell and monitored . However , she will not face charges , he said . `` The law specifically allows for no desire to prosecute . '' Aguilera was released about 7:30 a.m. ( 10:30 a.m . ET ) after passing a sobriety test , he said . Rutler 's bail was set at $ 5,000 , he said , not the $ 30,000 reported on the sheriff 's website . He said Rutler was in the process of bailing out of jail Tuesday morning . The car was pulled over after authorities noticed it `` driving erratically , '' he said . Aguilera divorced Jordan Bratman earlier this year .
