Jennifer Lopez celebrates birthday at her new estate

OHMYGOSSIP — Jennifer Lopez knows how to have a good time. The sexy singer celebrated her 44th birthday at her new Water Mill estate Saturday, according to New York Post gossip column Page Six.

Sources say Lopez’s family friendly “American barbecue” included “lots of mojitos,” a trampoline for guests and their kids, water balloons and sack races, where, “the clear winner was [J.Lo boy toy] Casper Smart.”

Guest in attendance included Alicia Keys, police commissioner Ray Kelly and Lopez’s manager Benny Medina, Epic Records chief L.A. Reid and CAK Entertainment head Charles Koppelman.

Sources recently revealed that Casper is acting like he’s the father of Emme and Max, the star’s 5-year-old twins by ex Marc Anthony.
