Rihanna, Lindsay Lohan Attend Britney Spears' LA Show

Despite the odd property invasion, Britney Spears has had a successful homecoming.

For the singer's stop in Los Angeles, on her International Circus Tour, celeb pals turned out to support her at Downtown LA's Staples Center.

The night featured bold names, bolder dance moves and even a little Chase Benz action.

On her official Twitter page, Spears' manager Adam says Rihanna, Lindsay Lohan, Jamie Pressly, Victoria Beckham, Queen Latifah and Gabrielle Union all came through for the performance. Representing the boys was veteran porn star Ron Jeremy, Howie Dorough of Backstreet Boys and actor Alan Cumming.

An enthusiastic crowd rocked with Britney for almost two hours.

"She flipped the bird twice during 'Piece of Me,'" a concert-goer tells RadarOnline, "and only addressed the crowd once saying, 'What's up, Los Angeles?'"

In regards to rumored paramour and backup dancer Benz, our onlooker says the pair were separated all evening on stage, with Britney shooting him a few looks during the track "Boys."

"He seemed hyper-focused on her but they never danced near each other, perhaps on purpose," says our spy.
