Christina Aguilera Delays 20 Date Summer Tour for New LP 'Bionic'Pop star busy with filming new movie, needs more time to rehearse Just two weeks after announcing her Bionic summer tour, Christina Aguilera has postponed the entire trek until 2011. The singer says she needs to focus on promoting her new album and is tied-down with commitments to the film Burlesque, in which Aguilera has a starring role. "[Aguilera] 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," said Live Nation, who was promoting the tour, in a statement. The rescheduled dates will be announced later this year. Also, they weren't even arenas. They were Amphitheaters.
