Christina Aguilera said she’s been doing things that she “normally won’t do” - and this might apply.

Although the singer was set to begin a 20-city tour on July 15, Aguilera has decided to postpone those stops until sometime next year.

While most have been blamed lukewarm response to her single “Not Myself Tonight” for the delay (the song currently stands at #89 on the iTunes chart), Live Nation claims the singer is simply too busy.

“[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,” the concert promoter said in a statement.

Huh - maybe Christina should have thought of that before she announced the tour? It’s not like she didn’t already know that Bionic would drop on June 8 or that Burlesque would open in theaters on November 24.

Hopefully Aguilera can find some time in her packed schedule to keep to her commitments this week. She’s scheduled to be on the American Idol finale this Wednesday.
