Source: Rehearsal Gave Britney A Boost Of Confidence



Just what the doctor ordered!

You know what I mean...

Britney may have gotten that boost of confidence she needed to perform her heart out on her upcoming "Circus" tour which launches today in New Orleans.

Britney was "totally killing it," said a source to x17online.com regarding Britney's private rehearsal for her family last Saturday in New Orleans.

Great news! Because last week a source close to Britney told BreatheHeavy Brit felt not ready.

"Although a source at the show says Brit was way nervous before going on, 'she got such positive feedback that she’s a lot more confident about her performance.'"

Tour launches tonight!
