The world was on baby-bump watch over the weekend when Jessica Simpson walked down the aisle as Maid of Honor in her best friend CaCee Cobbs' wedding to Scrubs star Donald Faison.

Unfortunately, the bulky black bridesmaid dress did a pretty good job at concealing what Jess is reportedly hiding when she was photographed walking arm-in-arm with groomsman and fellow Scrubs cast member Zach Braff.

Considering Jessica just gave birth this past spring and shocked the world by losing over 70 pounds with her Weight Watchers deal, this might not exactly be the best time for her to get knocked up again!

However, baby rumors aside, the engaged star was super supportive of her longtime BFF, tweeting, "I was the maid of honor last night for my BF . She was the most beautiful bride I have ever seen in my life!"

With weddings on the brain, maybe CaCee's big day means a step towards Jessica's own wedding to fiancee Eric Johnson. The couple has been engaged for two years, but put off their wedding for the birth of their daughter Maxwell. If there is another baby on the way, we might have to wait awhile for this one!

Can you see a baby bump on Jessica?
