After the 2014 U.S. Open women's final match, Caroline Wozniacki took the microphone on Ashe to thank her family, trainers and friends for supporting her throughout the tournament, but she also turned to her friend and title winner, Serena Williams, to say a few words. "You are an unbelievable champion and an inspiration to me on and off the court," Wozniacki said. "And you definitely owe drinks later."

During a press conference after the match, Serena confirmed that she would buy a few cocktails, and later that evening, the two pals -- plus SI Swimsuit model Gigi Hadid and singer Joe Jonas -- took to Instagram to pose for post-match party selfies during their night out in Manhattan.
