Anthony Joshua headlined the event and comfortably defeated Otto Wallin, while Deontay Wilder was handed a shock defeat to Joseph Parker, with plenty of celebrities in attendance at the evening in Riyadh, Saudi Arabia. 

And there was a star-studded cast of fans inside the Kingdom Arena with Ronaldo and McGregor arriveing ahead of the biggest fights of the night as they soaked up the atmosphere. 

The pair were even seen in a video walking around the ring, with McGregor turning to the Portuguese superstar telling him 'It's a small ring' with Ronaldo concurring with the UFC star.
