Tennis bad boy Nick Kyrgios has opened up on some of his wild conspiracy theories to YouTuber Logan Paul.
Kyrgios, 27, continues to split opinion and has been involved in a series of incidents over the years, including explosive court outbursts and being caught partying on the eve of major tournament matches.
He is currently sidelined with the knee problem that ruled him out of the Australian Open and sat down with Paul to discuss a number of interesting topics on his podcast Impaulsive.
On the agenda was Kyrgios 'mad' interest in conspiracy theories, as he was asked if he thought the world was flat. Smiling, the Aussie said: "I don't know what to believe anymore."
Kyrgios went on to suggest he could "chat for hours" with Paul on such theories and went into much more detail when discussing the Egyptian pyramids.
He added: 'I don't think the pyramids are man-made. The doors are pretty big, and we as humans don't need doors as big as those ones."
An impressed Paul insisted he shared the belief, asking: "How do they line up in perfect symmetry all around the earth?"
The pair, alongside fellow hosts Mike Majlak and George Janko, also discussed the prospect of mankind never landing on the moon before Kyrgios made a bizarre revelation about his ritual watching the popular show.
"I can't believe I'm doing this right now to be honest. I'd watch you guys on TikTok in my bed like half naked in my bed. And now I'm sitting here," he added.
Kyrgios also went on to insist ally Novak Djokovic is the best tennis player of all time, pulling clear of Roger Federer and Rafael Nadal.
He added: "I don't like comparing. It's like we take them for granted by always comparing them rather than appreciating how good they are.
"Djokovic wins the Australian Open and we are comparing him to Nadal immediately. Why do we do that? But statistically, Novak is the best."
Paul is set to head to Saudi Arabia to be in his brother Jake's corner for this weekend's eagerly-anticipated fight against Tommy Fury.
