Olivia Munn, who reportedly had “amazing sex” with Justin Timberlake while he was still dating Jessica Biel, encouraged a crowd at club Pure in Las Vegas Tuesday night to have their own one-night stands. While raising a glass of Skyy Infusions Dragon Fruit vodka, Munn yelled, “Who is going to have a random hookup tonight?” as the crowd cheered. The raven-haired correspondent for “The Daily Show” partied with new pal Selita Ebanks, and after the two danced and took photos of each other, they exchanged phone numbers at the end of the night.
