Quite a shindig J.Lo got going on for her husband! On the same day Jennifer Lopez successfully completed her first triathlon in Malibu, the sexy artist threw a big and splashy 40^th birthday party for Marc Anthony.

However, she kept the planned bash a secret and made use of all of her acting skills in order to hide everything from her spouse, J.Lo reportedly told PEOPLE magazine. As his anniversary approached, Marc Anthony kept on asking the beautiful star how they would celebrate the event. “The Wedding Planner” actress did not disclose her intentions and even told Anthony that her schedule was very busy and “that I might not be able to do anything,” PEOPLE reported.

Actually, Jennifer Lopez had arranged a 1940’s Cuban nightclub themed bash at the Bowery Hotel in New York City. After finishing all three sections of the competition (swimming, running and biking) and claiming the fifth spot in the celebrity women’s category at the Nautica Malibu Triathlon on Sunday, J.Lo got on a plane together with her husband and flew to New York. The singer/actress reportedly told her husband that they were going to have dinner with Katie Holmes so as to celebrate her upcoming Broadway debut.

Marc Anthony was astonished and could not believe his eyes. And he had every reason not to. The hot party featured stripper Dita Von Teese, salsa, mojitos, as well as showgirls.

All the guests enjoyed the out-of-the-ordinary shindig, including actress Brooke Shields and her husband, Chris Henchy. PEOPLE cited Shields as saying: “Jennifer is amazing. I did a triathlon once in college but for me a triathlon is now eating, drinking and sleeping.”

After the party, the beautiful couple and their twins headed for the coast of Italy and Greece. It’s a well-deserved vacation for the four of them.
