Vinnie Jones -- I'm Team McGregor ... 'Of Course'

Tough guy respects tough guy.

Vinnie Jones says when it comes to UFC fighters, he's all about Conor McGregor.

Vinnie joins a huge list of celeb McGregor supporters -- one that already includes Shaq, Arnold Schwarzenegger, U2's The Edge, Gordon Ramsay and many many more.

It'll be interesting to see if Nate Diaz can rally up some celeb support before the two do battle at UFC 196 this weekend.

One thing's for sure ... Nate's bandwagon will certainly fill up if he wins.
