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."
