Ever since Jennifer Lopez kicked off her It's My Party tour in June, she's delivered a handful of memorable moments on stage. While performing in cities all over the world — including NYC, Israel, and Turkey — the 50-year-old singer has especially shared a few precious memories with loved ones. Not only did she croon a duet with 11-year-old daughter Emme during the very first show in LA, but she also honored fiancé Alex Rodriguez by singing to him on stage for his 44th birthday in July. And every night, she's managed to look absolutely stunning while belting some of her classics, such as "Love Don't Cost A Thing," "Waiting For Tonight," and "I'm Real," as well as her newer hits, including "Medicine," "El Anillo," and "Limitless." Ahead, check out some of the best snaps from the It's My Party tour!
