Christina Aguilera has cancelled her upcoming North American tour to instead talk up a film.

A press release from Live Nation suggests the tour has been delayed because of her film commitments. "due to prior commitments that the singer had made to her film Burlesque and to the promotion of her new album Bionic," a statement reads.

Weird, isn't a tour the best thing to promote an album and a film just a side-project?

A spokesperson for Aguilera said she needed more time to rehearse for the show and a month before the start of the tour she needed more time.

The Christina Aguilera tour was due to begin in July. New dates have not been announced.

Aguilera's new single 'Bionic' failed to connect with US fans, peaking at no. 23 on the US chart.

The album 'Bionic' will be released on June 8.
