Women’s World No. 1 Aryna Sabalenka has not only taken up men’s 24-time Grand Slam champion Novak Djokovic’s dancing challenge at the French Open, but has actually outperformed him.

After his second round win over Valentin Royer, Djokovic, 39, kicked off the fun challenge by doing Michael Jackson’s famous moonwalk to his Billie Jean track while coming down the stars at Roland Garros. The Serb then mocked Sabalenka, 28, saying, “Can’t beat that.”
