'Circus' Tour director: "She's in great shape, she loves being on stage"

Tour director Steve Dixon admits being able to bring her family was one of the reasons Britney is finally touring here (Australia).

"Part of her new life is balance," Dixon told the Sunday Mail. "The boat (carrying the show) takes 30 days to get to Australia and during that time she'll be in the studio and doing video shoots, but also having down time with her kids."

The Circus: Starring Britney Spears, is the controversial star's first tour in five years and Dixon promises she won't disappoint diehard fans who have waited 10 years to see their idol perform. "This is the biggest pop show ever and people love her, they love the show," he said.

With nine costume changes - some of which take the pop diva as little as 15 seconds - all in keeping with the Circus theme, Britney takes centre stage as Ring Master.

But critics will no doubt be watching to see if the show is much more than just smoke and mirrors.

"She's in great shape, she loves being on stage - it's her favourite part of the day," he said.
