Jessica Simpson on her second pregnancy: 'Protection was just thrown out the window'

jessica-simpson-pregnant-again-ellen.jpg Jessica Simpson isn't being shy about the fact that her current pregnancy was an accident -- albeit a happy one. "I don't know, apparently protection was just thrown out the window," she says on Wednesday's episode of "The Ellen Degeneres Show". "We're happy. We were definitely extremely shocked... Maxwell was our focus and then I was puking and lying on the couch."

While she says her first pregnancy was easy and she felt fine, she's been feeling more ill this time around. She says that her Weight Watchers weight-loss program might have influenced the change.

"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," she says. "The first pregnancy I like 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."
