Jennifer Lopez is back in shape - and how! Barely seven months after giving birth to twins, J-Lo showed off her shapely post-pregnancy body by competing in the triathlon in Malibu, CA.

The 39 year old singer finished the gruelling event which included running, swimming and biking in 2 hours, 23 minutes and 28 seconds. Her husband, Marc Anthony, was on the sidelines, cheering her on. There were several other celebrities who participated in the race, including actors Matthew McConaughey and Jon Cryer.

Update:

J-Lo and family left soon after to reportedly celebrate Marc’s 40th birthday at a New York Hotel.

A sign on the Pasadena eatery says it closed down on July 1st “until further notice.” Madre’s had been in business for over six years — a lifetime in the world of celeb restaurants. In contrast, Britney’s NYC joint NYLA lasted less than a year.

A rep for Jennifer has yet to comment.

Update:

J-Lo went out shopping with hubby, Anthony, a couple of days ago. She seemed to have come with an intent to buy the entire store of Gucci products on sale.
