Jennifer Lopez [1] was surrounded by her loved ones as she wrapped up her All I Have residency in Las Vegas on Saturday night. After giving an incredible performance on stage, the singer threw a star-studded bash at the Planet Hollywood Resort & Casino. In addition to having boyfriend Alex Rodriguez [2] by her side, J Lo was also joined by her daughter Emme, 10 [3], niece Lucie Wren Lopez-Goldfried, 10, and Alex's daughters, Natasha, 13 and Ella, 10, on the red carpet.

During the afterparty, Jennifer couldn't help but gush about her supportive boyfriend [4]. "Listen, to have a partner who's that supportive, who comes to that many shows — we all know what it's like to be in show business. It's a grind," she told ET. "It's being away a lot and he really makes the effort, so do I, to be there for each other and it means a lot to me." While Jennifer made sure to give Alex a special shoutout during her performance, she also gave a friendly shoutout to her ex, Sean "Diddy [5]" Combs, who was sitting in the audience. Jennifer and Diddy, who dated from 1999 to 2001 [6], even shared a sweet embrace during her afterparty.
