“LOS ANGELES (Reuters) – Dolly Parton’s breasts may be two of the wonders of the entertainment world, but the country music icon says they are a pain in her back.Parton, 62, said on Monday she would postpone her upcoming North American tour after doctors told her to take it easy for six to eight weeks to rest her sore back.

“Hey, you try wagging these puppies around a while and see if you don’t have back problems,” the folksy singer-songwriter said in a statement.

The tour was due to begin on Feb. 28 in Minneapolis, two days after the release of “Backwoods Barbie,” her first album of mainstream country music in 17 years. She hopes to hit the road in late April.

Parton, also famous for her big voice, big wigs and big smile, has long joked about her famous bust. When she received a songwriters award in New York last year, she noted that she’s been known for two things throughout her career.

“I’m talking about my music and my lyrics,” she said.”
