Jessica Simpson explains her larger than average baby bump: “I have a lot of amniotic fluid”

Jessica Simpson has put her extremely blooming figure down to the fact that she has a lot of amniotic fluid.

Jessica Simpson, 31, denied on several occasions that she is having twins because of her ever-increasing size.

The singer told Jimmy Kimmel last night that she had been told by doctors that the excess fluid was to blame for her larger than average baby bump.

Last week Jessica Simpson told chat show host Ellen DeGeneres that she still has a month to go, being due to give birth on April 20th.

Jessica Simpson joked: “I feel I have a bowling ball sitting on my hoo haa!”

The singer then added candidly: “Apparently I have a lot of amniotic fluid, so whenever my water breaks it will be like a fire hydrant!”

Jessica Simpson also spoke about how she and fiancé Eric Johnson met, and when they are planning to tie the knot.

She said: “Eric feels like my husband already, we are just doing it a little bit backwards. We met at my house – he just came with one of my friends to my house, we were watching March madness or something.

“He came over and we sat on my stairwell and talked and I just haven’t let him leave!”

Jessica Simpson’s interview came as she was promoting her new TV show Fashion Star, and just a day after her baby shower.

Talking about the baby shower, which was attended by her sister Ashlee Simpson and famous friends including Ellen Pompeo and Jessica Alba, Jessica said: “I just had a baby shower yesterday which was unbelievable.

“It was a Charlotte’s web thing – we had a whole fair. We had fried Oreos.”

Asked by Jimmy Kimmel if she was nervous about giving birth, Jessica Simpson said: “No, I’m ready to push!”
