Jennifer Lopez to design exercise clothing

Jennifer Lopez is set to design her own range of exercise clothing.

The 'Do It Well' singer - who gave birth to twins Max and Emme in February - wants to create a line of affordable clothes that women can feel comfortable in while working out.

A friend of the star - who already has three other brands in her fashion empire J.Lo, Sweetface and JustSweet - said: "She has some street gear already in her lines, but she wants something exclusively for sneakers, yoga pants and dance gear.

"She wants it to look great in the gym and in the street, and to be affordable and functional."

Following the birth of her twins, Jennifer splashed out $50,000 on a home gym to help her lose her baby weight after gaining almost 50lbs during her pregnancy.

A source said: "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."

Jennifer, 38, is also planning to start using food delivery programme Fresh Mommy, an all-natural food company which provides expectant or new mothers with healthy meals.
