Jennifer Lopez dancing to stay in shape

Jennifer Lopez dances to stay in shape. The singer-and-actress has reportedly stepped up her workouts since taking on a role as a judge on US TV show American Idol but friends insist she never finds going to the gym a chore.

“Jennifer has amped up her workout routine by running three miles a day, five days a week,” a source said.

“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.

“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.

“I think if everyone had that much fun working out, no one would ever dread the gym.”

According to pals, the 41-year-old superstar’s hard work has paid off.

“She lost nearly 10lbs before ‘Idol’ began filming and she’s kept it off,” said the source.

“She’s over 40 and looks hotter than ever.”
