(Cover) - EN Showbiz - Jessica Simpson has discovered her love for "seasoning salt".

The 31-year-old singer and fashion mogul is currently expecting her first child with fianc Eric Johnson.

Her pregnancy cravings are becoming increasingly specific.

"Kraft mac and cheese with Lawry's seasoning salt is the breakfast for pregnant champions!!! (sic)" Jessica posted on her Twitter page on Thursday.

Salt has been one of Jessica's preferred flavours throughout her pregnancy. Earlier this month the star shared her dish of the week on American television series The Rachael Ray Show.

"This week it's peanut butter and jelly sandwiches, toasted," Jessica told Rachael. "And then, I'll put some salt on my hand like I'm taking a tequila shot and then take a bite of the sandwich."

Although Jessica reportedly loves eating for two, the star does not want to go overboard.

She has put on 30lbs since the start of her pregnancy and is hoping not to gain any weight beyond 35lbs.

Jessica hired a personal chef this month in order to help moderate her calorie intake.

Jessica will deliver her baby early next year. (C) Cover Media
