Jessica Simpson 'craves sugar during pregnancy'

Jessica Simpson has said that she is craving sugar during her pregnancy.

The singer and actress, who is expecting her first child with fiancé Eric Johnson, insisted that she is not worried about gaining weight.

"I had a buttered Pop Tart this morning," Simpson told Extra. "I'm eating a lot of stuff that I ate in my childhood. Kraft Mac n' Cheese, Pop Tarts, Cap'n Crunch. Everything's filled with sugar."

She added: "I'm like, 'Yeah, I can do it. We'll worry about the rest afterwards'."

Simpson recently praised Jessica Alba's post-pregnancy body, saying that she hopes to look like the actress after she gives birth.

The 31-year-old also revealed that she has yet to learn the sex of the baby.

"I feel like it's already going to be a shock, like, whoa I just pushed that out, you know?" she said.
