You're going to have to wait until next year to see [artist id="509026"]Christina Aguilera[/artist] live. The singer announced on Monday that she was calling off plans for an already announced [article id="1638749"]summer tour[/article] to promote her upcoming Bionic album and pushing the dates back to an unspecified time in 2011.

Citing a busy schedule that includes her involvement in the film [article id="1628465"]"Burlesque"[/article] (in theaters this November) and promotional duties for the June 8 release of her new album, [article id="1634692"]Bionic[/article] -- which leaked onto the Internet on Monday -- Aguilera's camp issued a statement about the postponement. "The singer felt she needed more time to rehearse the show and with less than a month between the album release and tour dates this wasn't possible," it reads. New dates for the tour are expected later this year. A spokesperson for tour promoter Live Nation could not be reached for additional comment at press time.

The tour was slated to kick off on July 15 at the Mohegan Sun Arena in Uncasville, Connecticut, and wrap up on August 19 at the Verizon Wireless Amphitheater in Irvine, California, and was to feature opening act Leona Lewis. The singer's first new album since 2006's Back to Basics has gotten off to a modest start, with first single [article id="1638840"]"Not Myself Tonight"[/article] peaking at #23 on the Billboard Hot 100. The accompanying transgressive video has stirred up controversy due to claims by [article id="1638192"]Lady Gaga supporters[/article] that it borrows some of the reigning pop diva's signature moves.

Your best chance to see Aguilera in the meantime is to tune in to Wednesday night's [article id="1637499"]"American Idol" finale[/article] and the June 6 [article id="1638351"]MTV Movie Awards[/article], where she is also scheduled to perform.
