Britney Spears: 'I'm Really Excited' for My Tour!

Britney Spears gives ET a sneak peek at her upcoming Femme Fatale tour in a recent sit-down interview at her rehearsals.

“I’m really excited. Probably going to be extra nervous the day before but we’ve been working hard for two months now,” the 29-year-old pop princess shared.

Britney, who’s kicking off the tour next Friday (June 17) in Sacramento, Calif., also chatted about her two boys, Sean Preston, 5, and Jayden James, 4.

“They’re really confused with ‘Mommy the Star’ and [just] mommy, you know? So it’s really interesting to see. ‘Is that Britney Spears or is that you, mommy?’ I’m like, it’s the same person! It’s really sweet,” she said.
