Jessica Simpson finding it hard to disguise her jealousy about her sister?

Ashlee's news she is expecting her first child with husband Pete Wentz.
A source said: "Jessica has yearned for a baby for years. She's told friends
that she can't wait to be a mom and has even joked that if she has to,
she'll resort to making her hairstylist pal Ken Paves the adoptive daddy.
Jessica never imagined that her tomboy younger sister would have a baby
first. It would be very hard for her not to be jealous."
