Dolly Parton's big boobs are a real pain in the back!

London, Feb 13 : Country singer Dolly Parton's big boobs have forced her to postpone her concert tour in America.

The 62-year-old singer had to postpone her tour because her 40DD breasts combined with her tiny frame have created have given her a bad back.

She has been advised eight weeks rest by her doctors.

"You try wagging these puppies around a while and see if you don't have back problems," The Mirror quoted Parton as saying.

"But seriously, the doctors said I'll be as good as new in a few weeks. I can't wait to get back out there," she added.

The singer was set to kick off 13-day tour to America at the end of this month but now will be rescheduled.
