Britney Spears checks into rehab...again

Britney Spears entered rehab Tuesday after an unusual weekend that included shaving her head and getting a new tattoo.
Spears voluntarily checked herself into an undisclosed treatment facility, CNN has confirmed.
"We ask that the media respect her privacy as well as those of her family and friends at this time," Spears' manager, Larry Rudolph, said in a statement.
Since she announced her separation from Kevin Federline late last year, Spears, the mother of two young sons, has been seen partying with Paris Hilton, and her appearance has been increasingly sloppy.
On Friday night, Spears grabbed an electrical shaver at a San Fernando Valley hair salon and shaved her head bald.
Entertainment TV shows and Web sites reported Friday that she had gone in and out of rehab that week.
