Jessica Biel displayed her slim post-baby weight as the "Total Recall" actress went on a date night with husband Justin Timberlake during the special screening of "Meru" at the Red Studios in Los Angeles last Wednesday.

"Taking to the stage to introduce the movie, the Hollywood beauty cut a stylish figure as she stood next to her handsome beau, dressed in tight denim jeans and a chic georgette-like blouse," reported Daily Mail.

"She happily paraded her post-baby figure in the classy two-piece ensemble, while adding height to her statuesque frame with stylish patent heels," the report added. "With her dark tresses left in tousled waves, Jessica enhanced her striking facial features with flawlessly applied makeup."

Justin Timberlake, meanwhile, opted for a casual getup with a military jacket over a plaid shirt and a plain white tee. He completed the getup with a pair of chinos and white sneakers.

In an interview with E! News, he said that new moms can check out his studio Rise Nation in West Hollywood and burn as much as 800 calories for just 30 minutes.

He said their workouts are a good post-baby regimen, and Jessica Biel is just one example among many mothers who'd like to regain their pre-baby figure.

"This is a great for post-baby...Rise Nation is fantastic," he said. "Mothers, after having the kid, they really need to pay attention to the breastfeeding and stuff like that. She can't really lose everything 'cause she is breastfeeding. It's going to take a while. At least here, we aren't doing too much. She can kind of go at her own pace and it's fantastic."

Justin Timberlake's wife managed to achieve the sexy post-baby body through breastfeeding and also her Paleo diet, which reduces grains and sugars in the food intake. Jessica Biel has also lost weight in the past using the same diet.
