jennifer lopezJennifer Lopez is reportedly designing a new range of exercise clothes, inspired by her efforts to lose her pregnancy-weight.

The star already designs a number of fashion lines - including her junior line JustSweet and higher-end Sweetface range - but a source told OK magazine that she likes the idea of a collection with a specific aim in mind.

The source explained: “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.”

Jennifer and husband Marc Anthony welcomed twins Emme and Max in February.
