Dolly Parton is postponing her U.S. tour for six to eight weeks because of back problems created by her breasts, according to a statement posted Monday on her music Web site.

"I know I have been breaking my neck and bending over backwards trying to get my new Backwoods Barbie CD and world tour together, but I didn't mean to hurt myself doing it!" she said in a statement. "But hey, you try wagging these puppies around a while and see if you don't have back problems."

The tour was scheduled to start Feb. 28 in Minneapolis to promote her new album, "Backwoods Barbie." Tickets will be honored for the rescheduled dates.

"Seriously though, the doctors said I will be good as new in a few weeks, and I can't wait to get back out there," Parton said in the statement posted on DollyPartonMusic.com."See you soon, Dolly."
