Triathlon By Day - Party By Night!

Talk about a quick change! Straight from her amazing Malibu triathlon effort where she raised a staggering $127,000 for the Children’s Hospital of Los Angeles, Jennifer hopped a plane to NYC to celebrate hubby Marc's 40th Birthday party at NYC Bowery Hotel!

Of course there were tons of celeb friends on hand to help celebrate, like Brooke Shields and hubby Chris Henchy, Kimora Lee Simmons and Djimon Hounsou and a host of others we don't quite recognize (but we're sure they're famous in their own right!)

She sings, she acts, she dances, she swims, she bikes, she runs, she throws an amazing party for her husband, and all on a hurt foot -- is there anything Jen can't do?

Well, except for guest judge Project Runway, of course!
