Christina Aguilera announced yesterday that she had canceled the summer tour for her new album Colonic Bionic to focus on her acting career. Live Nation released the following statement:

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.’ 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.

But of course, that’s not the real reason it’s been “postponed.” The Daily Mail says

There has been speculation that the disappointing response to Aguilera’s new album and poor sales of concert tickets are the real reason for the cancellation.

Despite attempting to promote the new record by posing naked for the cover of GQ magazine and releasing a racy video for single Not Myself Tonight, Bionic only reached a disappointing number 23 on the U.S. album charts last month.

The reported poor sales will undoubtedly be a blow to Aguilera, who had attempted to reinvent herself for the new release. ‘Bionic’ is her first album since she took time off to have her son in 2008.

It’s been two years since she’s been on the radio? Really? Huh. I can honestly say I didn’t realize it’d been that long. It’s not like there was a conspicuous absence of Top Forty puke on the airwaves. The New Babylonian machine makes sure to maintain the ranks — one shitty pop artist is replaced by another shitty pop artist before you even noticed the first one went missing. Time to face facts, Xtina: you’re totally expendable. Just like the Alaskan coastline and West Virginia coal miners.
