Since her retirement in 2012, Clijsters has regularly played in the legends, champions, and invitation doubles events at all four Grand Slam tournaments. One of her matches in the 2017 Wimbledon ladies' invitation doubles event drew public interest for Clijsters inviting a male spectator onto the court to play a few points. The spectator, Chris Quinn, had suggested Clijsters try a body serve when she had asked the crowd whether she should serve left or right. Before playing the points, she gave Quinn a women's shirt and skort so that he could abide by Wimbledon's all-white dress code. A video of the incident has over four million views on YouTube.
