The hip-hop mogul threw a huge party on Wednesday night after the opening of his new movie, Can’t Stop Won’t Stop: A Bad Boy Story. With Ciroc and Deleon as fuel, the rapper got a very small group of his closest famous friends together to party until the wee hours of the next morning.

Kendall Jenner and her big sister Kourtney Kardashian were there, along with Madonna, Chris Brown, and French Montana. According to a source who spoke to E!
