While revelers popped champagne bottles and lounged in and around the pool, Connor concentrated on spinning.
"He was hanging out with Caldwell and playing deep house songs," an eyewitness tells OKMagazine.com. "He didn't talk to any girls, or to anyone not in the immediate crew."
Though Connor was a little shy, the crowd loved the aspiring DJ's choices. "Everyone was really crazy and having the best time, jumping in the pool and spraying champagne," says the onlooker.
