McGregor wrote: "I went to see Mike Tyson last night in the Helix, Dublin, Ireland. I love and respect Mike Tyson. And I love the Helix. I won my first World Title here, and also my second.
"It was good to meet you Mike. You spoke some things about me in the past which I did not like and I was happy to speak to you face to face, put it to bed and have some fun.
"You are in good spirits and I was happy to see this! I will always have the height of respect for you! Some decisions you have made around your finances I do not agree with. As a fighter you must fight here. The most. And this is a fight that never ends. It is even a fight that we pass on to our next in line. Our blood line.
"Make sure you stay switched on with those around you at all times. You have good people around you now, I can tell. But stay switched on. Your Marijuana strain that you grow on your own ranch 'KO Kush' is really nice. It was an honour to taste it and I wish you and your team all the best with this endeavor.
"Just remember, if someone tries to rip you. Rip their nose off their face. You are a fighting icon and deserve endless love and respect! And from me, you will always have it!
"Don't let anyone take anything from you. You owe nobody nothing. It is you who is owed. Always remember that."
McGregor followed this up with another photo of himself laughing, holding what looks like a joint, writing: "Some giggle off that Cherry Pick Kush."
Fans have had a lot to say about the photo - with one tweeting: "Now this is a picture I never thought I'd see."
Another added: "Two living legends high on life."
Erm, yeah. Life. Sure.
Others decided to scold McGregor over the photo, saying that he shouldn't be on the 'Cherry Pick Kush' if he wants to keep his fighting game strong.
One person told him: "Get cannabis out ur lungs lad then maybe you won't gass out half way through fights all the time."
Someone else said: "Don't pls don't need u having energy in the later rounds!"
A third commented: "Then the man wonders why he can't win a ufc fight pissed up and high every other day..."
While some said that Tyson looked very 'unimpressed' in the second photo, others speculated that he was merely waiting for his turn...
