It was a girls’ night out – plus dad – for Britney Spears Friday.
Spears, in a black dress and sun-kissed blonde hair, told PEOPLE she’s doing “good” at Ed Hardy designer Christian Audigier’s 50th birthday party at L.A.’s Petersen Automotive Museum.
Jamie Spears joined his daughter, sitting on a couch about five feet away with his head resting on his hands.
Spears stayed about an hour and a half, smoking cigarettes on an outside patio, nodding her head to a live performance from Macy Gray, and abstaining from alcohol. When she left for the evening, her father joined her.
“I am friends with Britney,” Audigier told PEOPLE before the party. “She was at my office, I believe, three weeks ago. She got some presents for Jamie-Lynn and herself too. She got a ton of T-shirts, a ton of caps. She loved it.”
Spears left the party before Jackson, clad in a shiny blue shirt, came onstage to wish Audigier happy birthday.
Jamie Spears’ full-time job is now working for his daughter as conservator of her estate, court papers show.
The pop star returned home from a Costa Rican vacation at Mel Gibson’s house earlier this week.
