Jessica Simpson is indulging on grilled cheese sandwiches and onion rings during her second pregnancy.

The 'Fashion Star' mentor - who shed 70 pounds with a Weight Watchers program after the birth of her first child Maxwell seven months ago with her fiance Eric Johnson, 33 - was reportedly spotted tucking into the greasy fare at a bash to celebrate her best pal CaCee Cobb's 35th birthday earlier this month.

The 32-year-old singer - who has yet to officially comment about her pregnancy - is also said to have instructed her waiter to bring her ginger ale instead of her usual white sangria, according to

The blonde beauty is said to be thrilled to be pregnant again and recently made an offer on a new home in Los Angeles to accommodate her growing family.

Jessica was previously reported to have angered Weight Watchers for getting pregnant again so soon after they gave her $4 million to be the face of the company because they believe no one will want to take weight loss advice from a pregnant woman.

A source previously claimed: ''They're furious at Jessica. She was already on thin ice with them since she didn't lose enough for the first ad, when they had to shoot from the waist up.''
