Britney Spears First Post-Rehab Outing

Britney Spears made her public outing since leaving Malibu's Promises Treatment Center to attend a dance class and a sushi dinner with her girlfriends.

Spears participated in a one-hour hip-hop class at the Millennium Dance Complex in North Hollywood. She arrived wearing nude fishnet stockings with dance boots, black hot pants, a black long-sleeved shirt and baseball cap over her dark brown wig.

"The minute she walked in, she basically lit up the room," said the dance instructor. "I had no idea she was coming, so I was shocked."

"She did the choreography really well," the instructor added, "In fact, she came in and nailed it."

Spears then headed to Bel Air fusion Japanese eatery SHU Sushi House Unico and met up with three girlfriends around 10 p.m. Upon leaving, the pop star smiled at waiting photographers and gave a friendly wave before heading home alone at about 11:30 p.m.
