And the two were captured having a laugh after Ronaldo began shadow boxing in front of former world champion AJ.

The Manchester United legend - wearing a £3,350 Gucci jacket and short combo - took his seat next to Joshua earlier in the night.

But he was awkwardly BOOED after making his way into the arena, wearing a £1.2MILLION watch.

Ronaldo watched Fury, 35, controversially win a points verdict over ex-UFC champ Francis Ngannou, 37, in October.

And fans reacted hilariously to UFC icon Conor McGregor, 35, giving him an earful from ringside.

AJ has twice lost to Usyk, 37, but hopes to face Fury later down the line in a blockbuster Battle of Britain bout as he arrived ringside.

Although he sided with his former rival to win the fight of the century after 24 hard-fought rounds shared.

He told talkSPORT: "Well look I've fought Oleksandr Usyk so I can go only speak on what I have experienced from him.

"Phenomenal fighter, does everything to a tee and I would say he is going to do a really good job.

"I have never fought Tyson Fury so I can't really speak on how he will perform or what it is like to face him so only speaking on what I know I would have to say Oleksandr Usyk will be victorious."
