Troubled Britney has been in and out of rehab three times this year. It all started after she split from her husband Kevin Federline. She was then pictured partying with the likes of Paris Hilton and dancing in strip bars. Then the pop princess shaved her own head, got two new tattoos and attacked a photographer with an umbrella.

This erratic behaviour made her life come to a halt as she set out to battle her demons in the Promises Centre in Malibu California.
