Britney Spears’ long-awaited Circus World Tour opened to warm reviews in New Orleans on Tuesday night, but that pop tart will have to tighten up her lip-synching and really bring down the Big Top if she hopes to impress her toughest critic–her father Jamie!
Jamie, who serves as conservator of his daughter’s estate, has reportedly reignited shimmering tensions with the star after complaining that her ”timing was a bit off” during her opening night performance.

”Britney was very unhappy [about her dad's remarks] and told him he was full of shit.”

”I don’t know what he was smokin’, but he was very unhappy with Britney’s [first] performance of her ‘The Circus’ tour in New Orleans,” a Spears Family associate told The Chicago Sun-Times on Wednesday.
