Parton, Simpson bemoan large busts

Jessica Simpson has reportedly responded to a Twitter post made by Dolly Parton which bemoans her large bust.

Parton wrote that her 42-inch breasts, which she sometimes refers to as her "show dogs", were giving her pain, reports Us Weekly.

"Aahhh chiropractor... Hurts so good :-)," the 63-year-old said. "You lug these around and see if your back don't hurt!"

Simpson later responded by tweeting: "Amen, sister!"
