Jennifer Lopez spends $50,000 on a home gym

New mom Jennifer Lopez has spent a whopping $50,000 on a home gym to help her lose weight after gaining almost 50lbs during her pregnancy.

The 'Jenny From The Block' singer -- who gave birth to twins Max and Emme with husband Marc Anthony on February 22 -- has been working out as much as possible to get her figure back.

A source told Britain's Star magazine: "To motivate her, she's splurged out on a $50,000 home gym for her New York mansion. She's also consulted trainers, nutritionists and doctors, looking for the safest way to drop the weight in record time."

The singer, 38, recently revealed she used to worry that she would never have kids.

"You start getting older, you think to yourself, maybe [having kids] is just not meant for me," she said. "I knew there was nothing wrong with me.

"I knew that I could. Deep down, I really wanted it badly.

"Even after one year, two years, three years, you know, you start thinking to yourself, 'well maybe,'" added the star.
