Jessica Simpson Jealous Of Ashlee's Baby News?

As newly-engaged Ashlee Simpson tries to quash rumours she is pregnant with Pete Wentz’s baby, her older sister Jessica has reportedly been moping at the prospect of becoming an auntie.

The singer has reportedly been feeling broody and can’t believe her younger sister is set to become a mother before her, reports OK!

A source tells the magazine: "Jessica never imagined that her tom-boy younger sister would have a baby first," the insider explains. "It would be very hard for her not to be jealous."

Friends claim Jessica has wanted a baby for years, but since her public divorce from ex-husband Nick Lachey she has had trouble finding a partner to conceive with.

The source adds: "Jessica couldn't be happier for her sister but still can't help feeling jealous. She'd love to be planning a wedding with a baby on the way."
