Singer-turned actress Ashlee Simpson-Wentz told Women’s Health magazine that she wants people to stop calling her big sister Jessica fat.

Simpson-Wentz, who shows off her own svelte frame in the December issue of the magazine, said “It’s disgusting that people would say those things. My sister has an incredible body. I feel sorry for anyone who would judge her, because she’s one sexy lady.”

After she appeared in some unflattering photos at a chili cook-off in Florida in January, Jessica Simpson has been scrutinized for her weight gain over the past year.

Last year, the younger Simpson sister had a baby, Bronx Mowgli, with husband rock star Pete Wentz and shed her baby weight quickly. Although she is skinny now, she hopes that one day when she gains weight she will look as sexy as Jessica does.

Simpson-Wentz said, “There’s gonna be a time when I’m way curvier, and that’ll be sexy, too.”
