Yes. Jessica Simpson gained weight. That's what usually happens when you are pregnant. Nonetheless, she was the butt of a lot of jokes (pun intended) — until now. Jess recently made an appearance at Macy's in Costa Mesa with her lil' sister Ashlee Simpson to show off her new bod. Looks like her use of Weight Watchers is paying off! Good for her! As for Ashlee, she just looks like she's on that emaciated Olsen twin diet.
