Contradicting an earlier date reported by MTV, Britney Spears will bring her circus to town at the end of her American tour, which starts in her old hometown of New Orleans (the star helpfully pointed out on "Good Morning America" this morning that that's "in America") on March 3 and finishes up at the Allstate Arena in Rosemont on April 28.

The Pussycat Dolls open, and tickets go on sale Saturday at 10 a.m. through Ticketmaster at prices ranging from $39.50 to $150 per ticket plus fees -- that is, unless you want to spring for the "In the Zone" package at $349.50 per ticket plus fees, or the "Toxic VIP" package at $549.50 per ticket plus fees.

Taking a Big Top-themed stage on "Good Morning America" to celebrate her 27th birthday and the official release date of her sixth album "Circus," Spears danced and cavorted with a troupe of latex-clad, circus-goes-S&M dancers and lip-synced her way through the pitch-tuned, vocoder-distorted robot vocals of "Womanizer."

As these things go, it was better than her infamous melt-down at the MTV Video Music Awards in 2007. But that ain't saying much, and whether it's worth the nearly $600 Ticketmaster will take from you for that Toxic VIP ticket, well...
