Wale is being touted as the most sensitive rapper all over social media & here’s why…

(TMZ) Rap star Wale PUNCHED A GUY IN THE FACE at a WWE event Monday night — and judging by the way security rushed in to break it up, it appeared to be 100% REAL.

It all went down at “Raw” in Washington D.C. — TMZ spoke with eyewitness Jawn Murray from AlwaysAlist.com who says Wale was sitting right behind the announcers enjoying the show … when some fan seated nearby began taunting the rapper.

Murray says Wale eventually got up out of his seat and “the next thing I know Wale is putting the smackdown on dude. Punched him dead in his face. It was a full fight.”

Security rushed over and broke up the fight — and took everyone involved into a hallway. Moments later, Wale returned to his seat and began snacking on popcorn like nothing happened.

We’re told the other guy is also back in his seat.
