#8 Anthony Kiedis
Let's go from one celebrity rock star to another. Anthony Kiedis is the vocalist of the highly popular alternative/funk band Red Hot Chili Peppers, He's also a major goofball, having shown up at UFC 202 to watch Conor McGregor fight Nate Diaz, and acting like a nutjob in the process.
When the camera swung to him, he ate an apple in a rather strange manner (video linked below). In any case, Kiedis is in love with MMA and UFC; and has hence has invested $17 million in company shares. TJ Dillashaw also comes out to RHCP songs at UFC events.
