Nate Diaz says Jake Paul is a "spoiled f*ck" who needs to stop running his mouth before he gets beat up in real life.
And Nate ain't messin' around.
The UFC legend went off on Jake after watching a new video Paul posted Monday night going off on Conor McGregor and Dana White.
Diaz felt the video was disrespectful -- because it was -- and went to Twitter to warn Jake to pump the brakes before something bad happens.
"Jake Paul u need your ass beat for free u spoiled f*ck," Nate tweeted.
