"I thought it was gonna drop off easily because I had been in shape my whole life, but it wasn't," she told Entertainment Tonight in June. "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."
