With her new album Circus ready to go, Britney Spears told New York pop radio station Z100 yesterday that she's planning on embarking on a massive tour. "Oh definitely, next year," Spears said of her tour plans, adding that the jaunt would likely take her "around the world." The tour would be Spears' first large scale set of shows since 2004. Talking also about her three VMA award wins and the "Piece of Me" video, Spears said "It's a cool video, but I think by far I've done videos that are way better, so I was really shocked that it got the award." Spears also said that her role on Circus is complete and that she expects the album to be released December 2nd, her 27th birthday and the rumored release date for Jay-Z's Blueprint 3.
