In McGregor's Corner: Drake
Drizzy made a surprise special appearance when the Floyd Mayweather and Conor McGregor press tour stopped in Toronto on July 12.
The rapper stopped by McGregor’s dressing room before the McGregor-Mayweather press conference to give him some love before the big event.
We think it's safe to say that Drake is repping the Irishman for "The Money Fight".
In McGregor's Corner: Charlie Hunnam
Charlie Hunnam drew inspiration for his role in "King Arthur: Legend of the Sword" from McGregor.
The "Sons of Anarchy" star told The Independent, “We spent a lot of time looking at people out there in the world doing that. Particularly Conor McGregor was somebody that I drew a lot of inspiration from and that Guy and I discussed a lot.
Adding, “It’s all about self-belief and knowing what you’re capable of. And if you’re dialed in and focused to your true potential, then any obstacle is going to crumble before you.”
But can McGregor keep his focus inwards when he's in the ring with Mayweather Jr.?
In McGregor's Corner: Guy Ritchie
And speaking of "King Arthur," director Guy Ritchie spoke out about trying to get McGregor in the film.
Telling The MAC Life, “we even went after him for a part in the movie but he wasn’t having any of it."
The reason? McGregor, "Was training for a fight at the time, couldn’t take his attention away from that. But you can see in his presence, in his demeanour, he’s got that swagger, that real appealing cockiness," the director said before comparing McGregor to action-star Jason Statham.
In McGregor's Corner: Arnold Schwarzenegger
After McGregor thanked TIME magazine and Arnold for his appearance in the magazine's "100 Most Influential" list, the actor reciprocated his thanks, tweeting, "thank YOU for being such a great fighter, entertainer, and inspiration."
I think it's safe to say who Schwarzenegger will be cheering for come the fight.
In McGregor's Corner: Katheryn Winnick
It should come as no surprise, what with filming "Vikings" in Ireland, that star Katheryn Winnick "bumped into" McGregor.
And it's even less of a surprise that she wants to get him on the show, as she includes this caption with the image.
"Should we get @TheNotoriousMMA on Vikings?"
Our answer? Absolutely.
In McGregor's Corner: Dwayne 'The Rock' Johnson
One of the first celebs to tweet at McGregor following his win over Manny Pacquiao, The Rock sent his respect.
"Congrats @ufc for a spectacular NYC show!" Johnson tweeted. "Respect to the king @TheNotoriousMMA. Showmanship and skills on a precedent setting level."
In McGregor's Corner: 'Kingdom' Stars Nick Jonas + Jonathan Tucker
No surprise here! "Kingdom" stars Nick Jonas and Jonathan Tucker are big fans of McGregor.
The pair play brothers on the show and, if you've scrolled through Tucker's Instagram feed, you'll notice definite similarities to McGregor's brash style and cool confidence.
In McGregor's Corner: Rory McIlroy + Niall Horan
This photo should say enough.
PGA pro Rory McIlroy poses with McGregor and Niall Horan during the official UFC 202 after party.
After McGregor beat out Nate Diaz, he partied with his Irish pals at Intrigue Nightclub in Vegas.
In McGregor's Corner: Gordon Ramsay
He was ringside for McGregor's UFC 196 bout with Nate Diaz, and you can expect that celebrity chef Gordon Ramsay will be letting the expletives fly on Aug 26th, cheering for the Irishman.
Sly Stallone Roots Both 'Warriors' On
Without picking a side (just yet). Sylvester Stallone posted a tongue-in-cheek edit of the fight scene from "Rocky III", with McGregor's head in place of Rocky's and Mayweather's subbed for Mr. T's Clubber Lang. "This scene looks very familiar!" writes Stallone. "Conor is long long shot but in fighting strange things happen .. Floyd is going to be almost impossible to defeat!! Good luck and be safe to both Warriors!"
Mark Wahlberg + Sean 'Diddy' Combs Go Double-Or-Nothing
Who can forget the 100K wager Mark Wahlberg and Sean "Diddy" Combs made the last time Floyd Mayweather stepped into the ring.
Diddy, who was repping "The Money Team" took that bet, with Wahlberg donating 100K to charity on his behalf.
And it seems the pair are back and kicking it up a notch with a double-or-nothing wager in “The Bet 2”.
This time around Wahlberg is putting his money on Conor McGregor, with Diddy once again backing his man Floyd Mayweather.
Who will come out on top? You'll have to watch on Aug. 26.
In Mayweather's Corner: Travis Barker
A big UFC fan, Travis Barker was even on call to sound off on McGregor's UFC 203 bash against Nate Diaz.
The Blink-182 drummer later applauded (in emoji form) McGregor's post-win speech in his fight against Manny Pacquiao, but don't get it twisted, he's a HUGE Mayweather fan.
In Mayweather's Corner: Justin Bieber
Aside from the fact that Bieber's been training with the boxing legend for years, the singer has also accompanied Mayweather for more than a few walk-outs to the ring.
A pretty high honour for The Biebs, who, as 50 cent explained to MTV News, is a family favourite.
"When you feel like there's nothing to prove, then you can have Justin Bieber right there in front of you. Really, it's about [Mayweather's daughter] Iyanna. His youngest daughter's such a huge Justin Bieber fan."
In Mayweather's Corner: Jamie Foxx
A longtime supporter of the fighter, Jamie Foxx has most recently cast Floyd in his latest film.
Foxx also stepped into the ring to sing the national anthem during Mayweather's bout with Manny Pacquiao ...which some fans were less than pleased with.
In Mayweather's Corner: 50 Cent
50 and Floyd have a long history, including a beef back in 2014.
The rapper, who refers to Mayweather as "his little brother," recently explained to MTV News why he sometimes calls the fighter out.
The story goes, 50 challenged Mayweather to read a page of Harry Potter and in return 50 would pony up $750,000 as a charitable donation. You can imagine how, after it was revealed Mayweather is nearly illiterate, the story took a bad turn.
50 explained that in terms of his relationship with Mayweather, he's the fighter's voice of reason, saying, "He can make $200 million in 36 minutes. How do you tell him what to do? You don't. Sometimes, he's not right. You'll tell him, 'You're not right.' And then, you have that argument until he starts to look at it and say, 'He was right.'"
In Mayweather's Corner: David Hasselhoff
Who wouldn't want The Hoff in their corner?
In Mayweather's Corner: Sean 'Diddy' Combs
Maybe Mayweather's most BALLER friend - Diddy was so sure of Floyds ability in the ring he made a $250,000 bet with Mark Wahlberg on his fight with Manny Pacquiao.
That bet didn't turn out well for Wahlberg.
