Jessica Simpson is craving melons with salt sprinkled on them "like mad".

The star and her American football player beau Eric Johnson are currently expecting their first child together.

Jessica has revealed her unusual food desires ahead of the birth.

"I crave cantaloupe melons like mad. I can't get enough of them and have been eating whole melons in one sitting. I even sprinkle salt on them," she revealed. "I just crave salty and sweet."

Jessica is enjoying her pregnancy, although there are some downsides. The blonde beauty's body is going through some embarrassing changes.

"Well, I'd normally blame gas on the dog, but now I take full credit. It's like the baby's trying to find its way in there and pushing air through all the sockets," she laughed in an interview with Closer magazine.

"I don't have swollen ankles, just in the belly and boob area!"

Jessica is certainly enjoying the added attention from her fianc though. The American songstress says Eric, 32, is being extremely considerate.

"He's incredible and is going to be amazing," she gushed.

"He's always asking me what I want and what I need. I'm really loving all the back rubs and all the attention."

Although Jessica is enjoying her pregnancy, she can't wait until her bundle of joy arrives. She is thrilled about becoming a first time mother.

"[I'm looking forward to] dressing the baby, holding the baby," she said.

"Then again, I'm loving being pregnant, so I'm in no rush. I can't wait to be a mummy. I'm beyond excited."
