"It's disgusting that people would say those things," she told Women's Health magazine. "My sister has an incredible body. I feel sorry for anyone who would judge her, because she's one sexy lady."
Last month Fox aired, and later apologized for, a cartoon skit in which animated versions of the Dallas Cowboys mocked Jessica's weight. "Man, I still can't believe Tony dated Jessica Simpson, even after she blew up bigger than Flozell Adams!" said a cartoon Marion Barber.
Ashlee, who gave birth to son Bronx Mowgli almost a year ago, keeps in shape with several 30-to 40-minute workouts a week, but claims she's not worried about losing her lean look--and neither is husband Pete Wentz.
"There's going to be a time when I'm way curvier, and that'll be sexy, too," she said. "Pete isn't worried about stretch marks. He always makes me feel good."
Meanwhile, curvier Jessica is working hard to get in shape. She tweeted on Wednesday at her longtime personal trainer who whipped her into top shape for 'Dukes of Hazzard': "@madfit (mike alexander) why am i still hurting from our workout earlier? I'm getting old! See you tomorrow with a pouty face and sore buns."
Thursday post-workout she was hurting again and tweeted this picture of her icing her knees:
"@madfit look at what age can do to a total badass :( At least my legs will look good!"
