UFC's Nick Diaz Surfaces At Hollywood Club ... Props to Cher

Now that he can't fight for the next 5 years, UFC superstar Nick Diaz decided to spend a weeknight at the Hollywood club scene ... where he told he's happy Cher has his back!

Diaz -- who was hit with a 5 year suspension by the Nevada State Athletic Commission after testing positive for weed -- was leaving 1 OAK nightclub on the Sunset Strip Thursday night with a pretty thick unemployment beard.

So, we had to ask about Cher!

As we previously reported, tons of huge stars have expressed their outrage over Nick's punishment -- including Cher -- who's trying to rally people to force the NSAC to overturn the ban.
