This doesn’t sound too good! According to Live Nation, pop singer Christina Aguilera has put her upcoming 20-date North American summer tour on hold until next year. The tour was to support her new album Bionic, due in stores June 8th, and British Pop star Leona Lewis was going to be the opening act for all of the dates.

“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.”

The tour was set to kick off July 15th in Connecticut and end on August 19th in California, but a new round of dates will be announced later this year and current ticket-holders can get refunds wherever they bought their tickets.
