The biggest UFC fight of all time might just have the biggest celebrity guest list of all time -- with huge stars slated to be Octagonside when Conor McGregor takes on Khabib Nurmagomedov at UFC 229!
We're told Hollywood titans like Chris Pratt and Mel Gibson will be there alongside business moguls like Robert Kraft and Elon Musk.
Musk is an interesting one considering it would be his first major public appearance since agreeing to step down as CEO of Tesla.
