Ashlee Simpson Defends 'Sexy' Sister

She may not fit into her Daisy Duke shorts these days, but Jessica Simpson looks hotter than ever according to her younger sister, Ashlee Simpson-Wentz.

In the December issue of Women's Health magazine, Ashlee Simpson-Wentz says, "My sister has an incredible body. I feel sorry for anyone who would judge her, because she's one sexy lady." Jessica has taken quite a bit of heat for her curvier figure, from a body-bashing cartoon to the tabloid firestorm the erupted after she was photographed looking noticeably heavier while singing at a chili cookoff.

While Ashlee may think her big sis looks great, Jessica has enlisted the help of her former personal trainer who whipped her body into shape for "The Dukes of Hazzard." Apparently she's working hard because in a recent tweet to her coach, Jessica said, "Why am I still hurting from our workout earlier? I'm getting old! See you tomorrow with a pouty face and sore buns."

Meanwhile, Ashlee is receiving plenty of her own support about her post-baby figure stating that her hubby "isn't worried about stretch marks" and he "always makes me feel sexy." Even so, the new mom is reportedly working out several times a week. "I wanna look good [for me]," she tells Women's Health.

This isn't the first time the pop star has defended her sister's body. On her blog earlier this year, Ashlee posted, "I am completely disgusted by the headlines concerning my sister's weight....I find it completely embarrassing and belittling to all women to read about a woman's weight or figure as a headline on Fox News. All women come in different shapes, sizes, and forms and just because you're a celebrity, there shouldn't be a different standard."
