NATE DIAZ terrified a fan with a fake punch at Jake Paul’s fight with Tyron Woodley.
The UFC star was ringside in Florida as his team-mate Chris Avila beat Anthony Taylor, a former sparring partner of Paul’s.
And in typical Diaz style, he caused havoc in the building as a viral video emerged of him pretending to punch a man in the arena.
The frightened fan flinches and gets his drink everywhere, leaving fans in hysterics.
One said: “The beer made this hilarious.”
Another said: “I ain’t never seen a grown man flinch like that.”
One added: “That guy’s whole life flashed before his eyes lol.”
Even UFC president Dana White shared the clip on Instagram and tagged Diaz in the post.

Earlier in the week, Diaz, 36, clashed with Bellator champion AJ McKee, 26.
The American has one fight left on his UFC contract, and has teased a move into the boxing ring afterwards.
YouTuber Paul, 24, who knocked out Woodley, 39, in the rematch, called out Diaz and Jorge Masvidal, 37.
He said: “Masvidal and Nate Diaz, y’all are some bitches for leaving this arena.
“Because I know you don’t want that s***. I’ll take out both of y’all next.
“Just get out of your contracts with daddy Dana [White] and I’mma f*** them up too. Anyone, anytime, any place. It’s every f***ing day, bro.”
