Bionic Tour: Posponed Till 2011 For "Burlesque"

Christina Aguilera's summer tour has been postponed to 2011 because she does not have time to rehearse for it amid commitments to her first film, Burlesque and to the promotion of new album Bionic.

Meanwhile, the Grammy-winning artist is set to appear on the finale of American Idol on Wednesday, according to Aguilera's official Web site.

Those who had purchased tickets to Aguilera's planned summer concerts will be able to receive a refund, her spokesperson said, adding: "The singer felt she needed more time to rehearse the show and with less than a month between the album release and tour date this wasn’t possible. New dates will be announced later this year."

Bionic is due for release on June 8. Two days earlier, she is set to appear at the MTV Movie Awards. Her film Burlesque, which stars Kristen Bell and Eric Dane, hits theaters on November 24.

Aguilera's first scheduled summer concert was to take place at Uncasville, Connecticut on July 15 and her tour was set to end on August 19 in Irvine, California.

Then at 2011 it is!
