Jessica Simpson appears on The Ellen DeGeneres Show today, and the Fashion Star judge chatted about her second pregnancy, parenthood and she even cracked a joke about her weight.

When Ellen asked about baby number two, Jess joked, "I don’t know, apparently protection was just thrown out the window," adding that they were "definitely extremely shocked."

"Maxwell was our focus and then I was puking and lying on the couch," she added. "This pregnancy is the complete opposite [of my first]. Like with Maxwell, I felt amazing. 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."

On her weight gain when she was pregnant with Maxwell, Jess said, "[I] let loose and I kind of ate everything that I wanted to eat and I just really enjoyed it. This time around I think because I was doing Weight Watchers and I felt super healthy. I’m not really craving as much and I know how hard it is to get off so I’m trying to make healthier, wiser decisions."

After Ellen remarked, "That’s good," Jess said, "So I can gain as much weight and I will have a husband to be that loves me."
