Jealousy is a bitch!  Star magazine is reporting that Jessica Simpson is attempting to beat little sister Ashlee down the aisle.  I don't mean that literally, although a girl fight between the Simpson sisters right there in the church would sell a lot of magazines. And get a lot of FameCrawler hits.  Okay, I'll see what I can arrange...

Apparently Ashlee's pregnancy and engagement to Fall Out Boy Pete Wentz is bringing out the green-eyed monster in Jessica. “(Jessica would) love nothing more than to get married before Ashlee,” a source revealed to Star. “It upsets her that her little sister will be married and she won’t. She gets jealous when Ash gets more attention.”

Jessica is reportedly putting the pressure on her boyfriend, Dallas Cowboys quarterback Tony Romo, to tie the knot and is ready to take matters into her own hands. “She’s been showing him rings in magazines,” the source says. “She's been joking to friends that she should take Tony to Vegas, get him drunk and drag him to the Little White Wedding Chapel.”

Smackdown in (wedding) Aisle 3!
