Ashlee Simpson-Wentz wants people to stop calling her big sister Jessica fat, the singer-turned actress told Women’s Health magazine.

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

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

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

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

The Simpson sisters have been very vocal lately when it comes to snubs against their family. Last month, Jessica Simpson came to Ashlee’s defense when she was fired from “Melrose Place,” calling the show, “crap” through her Twitter account.
