Rudolph said in a statement, "Britney Spears has voluntarily checked herself into an undisclosed rehab facility today. We ask that the media respect her privacy as well as those of her family and friends at this time."

Us Weekly reports that Britney has been photographed smoking outside of Malibu's Promises Treatment Center. Promises is where Mel Gibson was treated for alcoholism last summer.

Britney checked into a different rehabilitation center - Eric Clapton's Crossroads Centre in Antigua - for one day last week before checking out. Upon arriving in Los Angeles again, she now infamously shaved her own head.
