Christina Aguilera Didn't See The Hangover II, She Was The Hangover II (PHOTOS)

Teen pop sensation turned mother turned host of the new hit TV show, The Voice, Christina Aguilera, was seen being carried out of a Hollywood club on Thursday night, because she was way too drunk to walk out on her own.

According to onlookers, the Burlesque star relied on boyfriend Matt Rutler to successfully navigate the club and make her way to the door.

Both Christina Aguilera and Matt Rutler were cited for being drunk back in March. Rutler was arrested and Christina was brought into the police station for "being severely intoxicated."

Sources say friends are concerned that Christina's drinking may be a very real issue. One even claims her heavy drinking is becoming a regular thing.

"She's nearly fall-down wasted every night," the source says.
