Christina Aguilera is postponing her summer tour until next year, citing her busy schedule in preparing her new album ‘Bionic’ and the film ‘Burlesque’. 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 date this wasn’t possible.”

‘Bionic’ will be released by RCA on June 8th, while the musical ‘Burlesque’ is scheduled to come out in November.

Could the troubling radio spins for her new album’s first single ‘Not Myself Tonight’ have played a factor? The single lost over 60% of its spins in a week and fell from a peak chart position of 14 to 38 on Mediabase’s Top 40 list (the song has fallen out of the Top 40 list as of this morning’s update).

Christina Aguilera has confirmed dates for her global tour in support of her new album ‘Bionic’, out June 8th. The 29-year-old announced 20 North American dates starting on July 15th. Aguilera will be joined by ‘The X Factor’ winner Leona Lewis. Tickets go on sale May 21st, and all fans who purchase tickets before June 4th will receive a download code for a digital copy the album on June 7th, the day before its official release.

Before going on tour, Christina will appear on the MTV Movie Awards on June 6th, the ‘Today’ Show Summer Concert Series on June 8th (the same day of her album’s release), ‘The Late Show with David Letterman’ on June 9th, ‘Live! With Regis & Kelly’ on June 10th, ‘The Early Show’ on June 11th, the ‘Today’ Weekend Show on June 12th, ‘VH1 Storytellers’ on June 13th and a surprise appearance or two in the coming weeks.
