On Saturday night, the 32-year-old DJ attended Jennifer Lopez's early 47th birthday party in Las Vegas, where both have residencies, and partied with the singer and fellow guests Kim Kardashian and French Montana. The rapper posted a photo of himself with the four, which shows the DJ's arm around the singer, who sported a sexy, semi-sheer brown Balmain catsuit. The bash took place after J.Lo's All I Have show at Planet Hollywood Resort & Casino, at her villa at Caesars Palace, and was hosted by her beau Casper Smart and manager Benny Medina, a source told E! News. John Stamos and Cristiano Ronaldo also attended.
"When Kim walked in Calvin saw her and stood up. He was clearly excited to see her and said 'hi' to Kim backstage," a source tells E! News, adding that the two "spoke for about 15 minutes."
