Jennifer Lopez celebrated her 44th birthday at her new Water Mill estate Saturday. The family friendly “American barbecue” plus “lots of mojitos,” included a trampoline for guests and their kids, spies said, as well as water balloons and sack races, where, “the clear winner was [J.Lo boy toy] Casper Smart.” Spotted lighting sparklers when a cake was presented to the singer were her “parents, kids, aunts and cousins,” a spy said, along with Alicia Keys, police commissioner Ray Kelly and Lopez’s manager Benny Medina, who made a touching toast to the birthday girl. Epic Records chief L.A. Reid and CAK Entertainment head Charles Koppelman were both seen rolling up to the bash in Bentley convertibles. Sag Harbor foodie Janet O’Brien provided the gourmet grub. Lopez — who reportedly paid $10 million for her 8,659-square-foot Hamptons home — also recently celebrated her birthday at Wall in Miami.
