The "Fashion Star" judge, 32, said the second pregnancy has been the "complete opposite" of her relatively complication-free gestation with daughter Maxwell Drew.

"I felt amazing," she said, recalling the ease of her first pregnancy. "Like, I could do everything, eat everything. Do whatever I wanted. I had a lot of energy.

"This time around... I'm like, exhausted, eating Tums. That's my snack of choice!" she added.

However, the fashion mogul said her fiancé, Eric Johnson, is supportive of her no matter how much she weighs.

"Apparently Eric still wanted me so... I can gain as much weight and I will have a husband-to-be that loves me!" she said.

As previously reported on AccessHollywood.com , news of Jessica's second pregnancy broke in late November 2012, and the bubbly blonde confirmed the happy news on Christmas Day.
