"I thought it was amazing. She was really great," said Sarah Ammann, a fan from San Francisco.
"She's the ultimate performer. She's definitely back," added Alicia Kennon of Brentwood, Calif.
Spears changed costumes and surprised the crowd by coming out of a speaker, dancing and singing "Big Fat Bass."
