Somebody needs a day planner...

Christina Aguillera has cancelled her world tour, within a few short days of tickets going on sale. But not because of poor sales or anything like that. Noooooo! She's just too darn busy, mostly with a film she's in with Cher.

"Immediately after wrapping production on Burlesque, I went directly back into the studio and then quickly started the promotional process for Bionic. With both the album press and film press I am booked the entire summer and need time to focus on the work at hand. After reviewing the schedule with my team, I realized there was not enough time to put together and rehearse for a proper show" -- Christina Aguillera

Who can't relate to that? It's happened to all of us at one time or another...

"Hey Brenda, I am soooo sorry for such short notice, but I gotta take a raincheck on lunch again. Yeah, I know, I know. It's been forever and we need to catch up on things (and we will! I promise!) but I just looked at my calendar and, damn it, I'm doing a movie with Cher. Augh! I don't know why I constantly do this; schedule appointments for important things that impact other people before remembering I'm in a movie with Cher. Maybe I should hire a team to mind my affairs. Ha ha! So sorry. My fault, totally." -- Me
