In a recent interview, Ashlee Simpson-Wentz shot back at the media for commenting on her sister’s weight.

“My sister has an incredible body. I feel sorry for anyone who would judge her, because she’s one sexy lady. It’s disgusting that people would say those things.”

Ashlee, who landed the cover of this month’s Women’s Health magazine, also added that she cannot wait to gain the pounds: “There’s gonna be a time when I’m way curvier, and that’ll be sexy too. What defines sexy is not someone’s weight. Personally I like curves. ... I wanna look good [for me]. I wanna feel good.”

The weighty backlash from Ashlee comes shortly after Jessica wrote an angry post on her Twitter regarding her sister’s swift departure from her show Melrose Place.

Those Simpson sisters sure do know how to get each others’ backs.
