The Australian stunned his girlfriend during a drug test.

Tennis' new documentary on Netflix has already been a talking point in the lead up to the Australian Open and with one episode focusing on Nick Kyrgios some fans got more than they bargained for in the feature. Break Point was released on Friday with the first episode going behind the scenes of Kyrgios' 2022 Australian Open campaign.

Kyrgios was able to lift his first doubles grand slam trophy last year when he teamed up with Thanasi Kokkinakis for glory. However, following their epic semi-final victory against the No.3 seeds, Kyrgios was pulled aside for a random drug test.

Cameras didn't follow Kyrgios into the bathroom for privacy reasons, but his girlfriend Costeen Hatzi was left waiting outside for him.

“They're just doing a urine test,” Hatzi said on camera. “He’s like 30ml under, so he has to keep drinking water.” Kyrgios is then seen FaceTiming Hatzi during the ordeal as he admits he is drinking more fluids.
