Jessica Simpson feels Dolly Parton's pain over having big breasts.

"Aahhh chiropractor... Hurts so good :-)" Parton, 63, Twittered late Monday. "You lug these around and see if your back don't hurt!"

Simpson, 29 -- who has called Parton an idol -- responded with a smile: "Amen, sister!" Simpson's breasts have long been the center of attention.

Her father Joe raised eyebrows when he praised her assets in a 2004 GQ interview.

"Jessica never tries to be sexy. She just is sexy. If you put her in a T-shirt or you put her in a bustier, she's sexy in both," he said. "She's got double D's! You can't cover those suckers up!"
