Well, that’s one way to celebrate. Serena Williams couldn’t help but let loose after taking home her first singles gold medal at the London Olympics, screaming and dancing on the court after defeating Maria Sharapova. And we can’t say we blame her. Williams became the second woman ever to achieve a career Golden Slam—winning all four of tennis’ Grand Slam titles (the Australian Open, the French Open, Wimbledon and the U.S. Open), plus an Olympic gold medal—and the first player to achieve a Golden Slam in both singles and doubles. The term “Golden Slam” was first established back in 1988, when Steffi Graf won all four Slam singles tournaments and the singles gold medal at the Olympics that same year—and she remains the only tennis player, male or female, ever to achieve that feat.
