What's Britney been up to since she left rehab? The singer was spotted out and about looking glowing and healthy (albeit in an array of different hats) after a month at the Promises clinic in Malibu. She went to an advanced hip-hop dance class with some girlfriends and then went out to dinner at a sushi restaurant. Dance instructor Darrien Henning explained, "I had no idea she was coming, so I was shocked." Brit's arrival caused quite a stir at the class, but she she settled in at the back and enjoyed the workout: "She did the choreography really well. All my students tried harder to get on their game." Britney was dressed in a pretty white dress and sunnies and donned various hats to cover her wig and shaved head. Meanwhile, she didn't attend estranged husband Kevin Federline's birthday party in Las Vegas, leaving the wannabe rapper to party with his ex-girlfriend and a group of other women. |
