For Halloween, anyway.

Some women go on diets to fit into their wedding gowns. For Jessica Biel, 24, looking like Catwoman is the motivation. On Oct. 13, while doing cardio at Pro Gym in Brentwood, Calif., Jess told her trainer she was “excited” about hosting an upcoming costume ball in LA — but a little concerned about her costume, an eyewitness tells LifeandStylemag.com. “She told her trainer to kick her butt because she plans to wear a skintight custom-made black-patent-leather outfit when she hosts the event,” the eyewitness says. “Jessica said her costume, which has a thin-strapped bustier, pants, ears and a tail, didn’t look quite right at her last fitting. She said, ‘I want it to look like Catwoman, and when I tried it on, it looked more like The Matrix, so they’re fixing it.’ ”
