Nick Kyrgios to Stan Wawrinka: "Kokkinakis banged your girlfriend, sorry to tell you that, mate"

Nick Kyrgios went out of bounds approaching the net in his match against Stan Wawrinka, uttering the above.

For some back story, Stan Wawrinka got divorced and there was plenty of rumor that he was dating female tennis player Donna Vekic (pictured below). Kokkinakis is Australian player Thanassi Kokkinakis, and last year, there were rumors linking he and Vekic as well (both played together as mixed doubles partners).
