Christina Aguilera has postponed her 20-date North American summer tour until next year, according to a statement from tour producer Live Nation. The singer was set to tour in support of her new album, "Bionic," due June 8.

"Christina Aguilera's summer tour has been moved to 2011 due to prior commitments that the singer had made to her film 'Burlesque' and to the promotion of her new album 'Bionic,'" according to a statement from Live Nation. "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."

A new round of dates will be announced later this year, and ticket refunds are available at point of purchase.

Aguilera's trek was scheduled to begin July 15 at the Mohegan Sun Arena in Uncasville, Conn., and wrap Aug. 19 at the Verizon Wireless Amphitheater in Irvine, Calif. British pop singer Leona Lewis had been tapped to open the concerts.
