The Simpson ladies have been through their fair share of ups and downs this past year, but one thing they can always rely on? Each other.

In fact, Ashlee, who’s reportedly set to make her Broadway debut as Chicago’s Roxy this December following the wrap of her role on Melrose Place, is defending her big sis in the December issue of Women’s Health.

“My sister has an incredible body. I feel sorry for anyone who would judge her, because she’s one sexy lady,” the actress, 25, says of Jessica, who’s made headlines for her weight fluctuation. “It’s disgusting that people would say those things.”

Jessica, 29, meanwhile, already returned the favor earlier this month, when she bashed the writers on her sister’s former show. “CW catching up on MP. Who writes this crap? i have had bad scripts to work with, but this? thank God my sister is amazing and got you some press,” she Tweeted.

Simpson-Wentz tells the magazine that even sudden career shifts don’t get her down anymore, especially now that her family is priority.

“[Being married] made me able to share more,” she says. “Now Pete and Bronx come first. It has humbled me.”

And, as for her own body image, Simpson-Wentz adds the only person she wants to look good for is herself – and her husband, of course. “Pete isn’t worried about stretch marks,” the mother of 1-year-old Bronx says. “He always makes me feel sexy.

“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.”

And her favorite way to stay in shape? “Bronx Pilates! And these [biceps] are from holding him. He’s in my arms all the time.”
