Jennifer Lopez dances to keep slim

London: She is known to have one of the best figures in Hollywood and pop diva Jennifer Lopez`s passion for dancing helps maintain her slim physique.

The 41-year-old singer-actress who is currently a judge on US TV show `American Idol`, enjoys exercising and her recent weight loss is down to high energy dance workouts with her trainer, reported Contactmusic.

"Jennifer has amped up her workout routine by running three miles a day, five days a week. But her true love is a dance workout. She has one of her choreographer friends meet her at a studio three times a week, where they put on loud Latin and pop music and dance and sweat for a full hour," said a source close to the `Get It Right` hitmaker.

"They just laugh and work out until they are drenched with sweat. They even have dance offs, taking turns to busy out some impromptu routines," added the source.

The `Maid in Manhattan` star has stepped up her workouts since appearing on the show and her hard work has paid off.
