Jessica Simpson shows off dramatic baby-weight loss in sexy Halloween costume

We have no idea what Jessica Simpson is supposed to be, but one thing is for sure: she looks fantastic! The new mom showed off her major weight loss (she reportedly has dropped 60 of the 70 pounds she gained while pregnant with her daughter) in a super-tight costume, which we can only describe as a sexy barbarian, as she posed with her fiancé Eric Johnson (in a "Braveheart"-inspired getup) and little "chicken," Maxwell. It was one year ago today that the singer-turned-fashion mogul announced she was expecting when she posted a photo of her "mummy" costume, a major hint at her impending motherhood.

Simpson, 32, certainly has good reason to be proud of her post-baby body. She has worked hard to regain her famous figure between participating in Weight Watchers (she's a spokesperson) and burning off the calories by hitting the gym four times a week with her personal trainer Harley Pasternak, in addition to walking about 14,000 steps every day. "In over 20 years, I've never seen as consistent a weight loss," he tells Us Weekly about his famous client. "Jessica's right where she needs to be … She's gotten so much stronger."

The famous yo-yo dieter has admitted that she enjoyed gaining the weight during her pregnancy. "I let myself indulge in everything I wanted," she told USA Today. "I wanted to be happy and eat what I wanted" … and she did just that.

But now, Simpson says, she's "eating less of everything" without depriving herself. With her daily allowance of 28 Weight Watchers points, these days she's indulging in fresh fruits and veggies (which are zero points) and the occasional fun-size bag of M&Ms to satisfy her sweet tooth.

"I feel like everybody can do what I am doing," Simpson told USA Today last month. "I'm not a supermodel. My body is not bouncing back like a supermodel. I'm just your everyday woman who is trying to feel good and be healthy for her daughter, her fiancé, and herself."
