Britney Spears's Cheering Section Includes Family and Kevin Federline

Britney Spears's comeback tour is getting rave reviews from those closest to the singer.

"Britney's whole family was there, her parents, [sister] Jamie Lynn, [brother] Bryan, his wife, her cousins [including] Laura Lynn [Covington], friends from Kentwood - everyone thought it was a fantastic show and she just nailed it," says a source close to Spears, referring to her kickoff concert Tuesday at the New Orleans Arena, the first stop on her 36-show tour.

Adds the source: "They all thought Britney was so amazing - her energy, her spirit."

Also in attendance: the singer's sons Preston, 3, and Jayden, 2, and their dad Kevin Federline. "He was there to support her as well," says the source, adding that the boys stayed backstage because "it's just too loud for them to watch."

The Cirque du Soleil-style show, which also got the thumbs-up from fans, marks the pop star's first tour in five years. New Orleans was the first stop for Spears, 27, who hits Atlanta on Thursday, followed by 10 shows on the East Coast.

"The show was completely sold out and it was just incredible," says the source. "Britney was just really happy."
