… with Richard Branson!!

It all went down at the Pendulum Summit for business leaders in Dublin, Ireland … where Conor was presented with a lifetime achievement award for his BIG money moves.
Branson joined McGregor onstage — and after some back-and-forth, convinced the UFC mega-star to bro out.
Not to be outdone, Rich ripped off his top too … and we gotta say, dude looks pretty frickin’ jacked for a 67-year-old gazillionaire.
The whole thing was kinda weird — but mostly awesome.
