Jennifer Lopez: Getting Body Back Took "a Lot of Work"

Here is what J. Lo had to say about losing the baby weight:

"It did take a lot of work," Lopez, 39, admits. "I thought it was gonna drop off easily because I had been in shape my whole life, but it wasn't. I gained about 50 pounds with my twins, and the first 30 dropped off like that, and I was like, 'Ha, this is gonna be so easy.' That last 20 -- that took a while."

Even she got caught up in the Hollywood hype of losing the baby weight fast.
