Citing a busy schedule leading up to the release of her new album and film, Christina Aguilera has canceled her summer tour, telling fans she'll be back on the road in 2011.

"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,'" Live Nation, the tour's promoter, announced in a statement. "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."

The singer's 20-date tour was scheduled to begin in July. Live Nation's website still lists Aguilera as one their "Top 10 Tours" this year, alongside 'American Idol' and Dave Matthews Band.

Aguilera has been working on 'Bionic,' which is only her fourth studio album, since 2008. The first single, 'Not Myself Tonight,' was released last month.

The other project responsible for bumping the tour is 'Burlesque,' which will mark Aguilera's debut on the big screen. She plays a small-town girl that moves to Los Angeles and begins work at a burlesque club ... run by Cher. The musical film will be released in November.

Well, with the most expensive tickets ranging from $150-250, I wouldn't be surprised if there were low sales. I hate when people charge insane prices, it's nothing but a slap in the face to fans.
