In Touch has exclusively learned that Britney Spears checked into the Beverly Hills Hotel under the name "Snow White" yesterday afternoon, just hours before the police were summoned to her home. But instead of the seven dwarfs, Britney had only one companion — her beau, photographer Adnan Ghalib. "The pair came in and got a room and she didn't want to use the name Britney," says an insider. The couple checked in at 4:45 p.m. and went straight to their room. But Britney isn't the only Snow White in the Spears family. Last year, the troubled pop star bought a teacup Chihuahua from Pets of Bel Air. She named the puppy Snow White!
