Kyrgios was representing Team World in the Laver Cup in Switzerland, where he was up against Grand Slam legend Roger Federer. And things seemed to be going well for the Aussie after he claimed the opening set 7-6 on a tiebreak.
But, after the third game in the second set, Kyrgios appeared to lose his form and his concentration as he dropped the game to the Swiss superstar.
And, when he returned to his chair during the changeover, he revealed to his team the cause of his sudden loss in form.
"I lost concentration," he said.
"I saw a real hot chick in the crowd. Like, I'm being genuinely honest, I'd marry her right now. Right now!"
