People.com: One of the few fans to see Britney Spears's dress rehearsal of her Circus show at the New Orleans Arena Monday night tells PEOPLE that the pop star did not disappoint.
"She really delivered," said Libby Davis, 27, of Baton Rouge radio station WFMF, which gave away tickets to the late-night rehearsal. "There were only 150 people there, but she put on a great show."
As for how Spears looks, Davis says, "Her body is definitely back. We could see her arm and leg muscles from where we were sitting. In typical Britney fashion, the costumes were pretty scanty. It was Cirque du Soleil meets Moulin Rouge."
Davis's group waited through the first dress rehearsal for family and friends, which they could hear but not see. Once inside, "Everybody was chanting, 'Britney, Britney, Britney,' screaming, 'We support you, Britney,' " says Davis.
"She put on the entire show as if it were a full house. She catered to us," adds Davis. "She even stopped during 'Womanizer' because she realized we couldn't see her. She said, 'Let's do it over.' "
Manager Weighs In
Spears's manager, Larry Rudolph, told Ryan Seacrest on his KIIS-FM radio show Tuesday that fans should have high expectations for the tour, which is sponsored by Virgin Mobile.
"This is a full-out, full-blown Britney Spears show," he says. "It is everything everybody would expect from her and more."
In terms of how her life on the road has changed with motherhood, Rudolph says Spears benefits from having sons Preston, 3, and Jayden, 2, with her. "[They] give her amazing inspiration and amazing strength."
Leading up to Tuesday's kick off concert Rudolph says Spears will sleep late, have breakfast in the early afternoon and arrive at the Arena about 4 p.m. where she'll get into hair and makeup. "And then, the performance," he says.
Davis feels lucky to have been able to see the intimate preview – even though the show happened so late that she didn't get home until 3:30 Tuesday morning.
"It was insane," she says. "But it was worth it."
