HOLLYWOOD - Britney Spears made her first public appearance since rehab on Friday--to take a dance class and enjoy sushi with friends.

The pop superstar checked out of Promises rehab facility in Malibu, California, last week and made sure her first Friday night of freedom was all fun.

Wearing fishnet stockings and dance boots, the singer took an advanced-level hip-hop class with instructor Darrien Henning at the Millennium Dance Complex in North Hollywood.

Henning tells People magazine his new student "lit up" the room.

The dance teacher says, "I had no idea she was coming, so I was shocked." He adds, "She did the choreography really well... She came in and nailed it."

After her dancing class, Spears joined friends at Bel Air Japanese restaurant SHU Sushi House Unico.
