Justin Bieber apparently knows what's going to happen in the fight of the century!

As far as sports psychics go we've seen them all! The football world cup in 2010 had an octopus, the rugby world cup had a parrot and a sheep and now the McGregor vs Mayweather fight now has a singer.

It's being billed as the fight of the century, MMA vs Boxing, Ireland vs the USA, Mcgregor vs Mayweather and so far the hype is living up to it. So who should we listen to for a detailed breakdown of what's to be? Who's the expert that's going to tell us where to put our money? Did you guess Justin Bieber? Neither did we, yet here we are.

Just look at that Conor McGregor dance above, if that doesn't say "I'm a big Conor McGregor fan" then we're a monkey's uncle, but nonetheless, Justin Bieber is adamant that Mayweather will not knock out Connor McGregor. Quizzed on whether he thinks Floyd will knock Conor out, he told TMZ Sports: "I don't think so. I think it'll be a good fight."

Speaking about Floyd - who is thought to be dating British reality TV star Abi Clarke - at the bash, Justin said: "I love this guy. I look up to him.

"Give it up for the champ."
