Why so coy, Jessica? Singer-designer and new mom Jessica Simpson wore a roomy all-black outfit yesterday as she walked through Los Angeles International Airport.

Simpson, who became a Weight Watchers spokeswoman in May just a few weeks after giving birth to daughter Maxwell Drew with fiance Eric Johnson, is set to debut her post-baby body Monday during Katie Couric's new talk show.

The big reveal on the first day of Couric's new show, "Katie," comes after Simpson told Us Magazine last week that she was just "10 pounds away from her pre-baby size." Sporting a loose tunic, black pants and a large purse that she held by her midsection, the singer made her way through LAX to board a flight for New York.

Simpson, 32, credits the points-based weight-loss program for her new figure. She also works out four days a week with celebrity trainer Hailey Pasternak. Couric's new show airs on ABC at 3 p.m.
