Former Crossing Jordan and Law & Order actress Jill Hennessy just debuted her body after giving birth to her second child in November. And well, it looks pretty good.

Hennessy credits nursing for losing her pregnancy weight: "When you are nursing a small infant it literally sucks everything out of you," the 39-year-old said at her first post-baby public appearance.

Yoga helps too, admited Hennessy who maintains that getting back into shape is not all fun and games.

"Yoga is a great thing, it really helps you get back into shape," she said. "It wasn't easy though. Trust me!"
