Jennifer Lopez, who made the rounds in NYC all last week for Fashion Week (and blew off celebrity guest judging duties for the Project Runway Season 5 Finale Fashion Show) managed to fly out to Malibu, CA to compete in the Nautica Malibu Triathlon yesterday before flying back to NYC later in the day Sunday for her husband’s birthday party. Here are pics of J. Lo and her zombie hubby Marc Anthony late Sunday night making their way to his surprise 40th birthday party at the Bowery Hotel:

Hours after completing her first-ever triathlon (she finished in 2 hours, 23 minutes), Jennifer Lopez got glam again. She flew to New York City with husband Marc Anthony to celebrate his 40th birthday at the Bowery Hotel. Party guests included Dita Von Teese and Kimora Lee Simmons. Anthony turns the big 4-0 on Tuesday. Lopez – who turned 39 in July — was all smiles, donning a white, empire-waist Marchesa gown on her way into the celebration. (By the time she left, she had changed into a taupe, silk frock.) Of course, Lopez had another reason to celebrate Sunday: She helped raise $127,000 for the Children’s Hospital of L.A. (Overall, the race earned $950,000 for charity.) “I feel really great and so glad I finished and that I made it out of the water but more amazing than that, I feel really great that we raised $127,000 for the Children’s Hospital [of Los Angeles] and hopefully it’ll go to good use,” Lopez told the crowd after finishing. Throughout the race, Anthony stood at the sidelines cheering on his wife. Lopez even stopped to kiss him between the biking and running portions of the race.

Wait, what? Why? It makes no sense that Marc‘s party would be on the opposite side of the country on the very same day of J. Lo‘s triathlon. Wouldn’t it have made more sense to either move the party date OR move the party location to SoCal? I mean … right? She did manage to fly from NY to LA … compete in a triathlon … then fly back from LA to NY all in one weekend. Maybe that was part of the race? Whatevs, I guess that’s love, y’all. Who am I to judge, I’m flying off to Iceland for my boyfriend’s birthday so … c’est la vie!
