Britney Spears checked into the Beverly Hills Hotel under the pseudonym Snow White hours before police arrived at her home to escort her to hospital. The troubled pop star is currently in hospital on a 72-hour psychiatric hold, after her psychiatrist summoned authorities to her home late on Wednesday night (30Jan08). In Touch Weekly magazine reports Spears was joined by paparazzi boyfriend Adnan Ghalib. A hotel source says, "The pair came in and got a room and she didn't want to use her own name." Ironically, Spears has called her new pet Chihuahua Snow White.
