Morgan Wallen made a pretty bold move before his concert in Ohio Friday ... because he's now completely bald -- as in no hair!!!
The country music singer walked out onstage at Ohio Stadium in Columbus after he shaved off his famous mullet with his head looking like a cue ball.
Morgan wore a red baseball cap ... but it couldn't hide the fact all of his hair was missing in action.
Check out video that surfaced on Tik Tok ... Morgan stopped to mention his new look in between songs, making light of the situation by saying, "I didn’t like the long hair anymore so I shaved it off." The crowd just hollered and laughed.
But some of his fans weren't having it and expressed their unhappiness with his transformation.
One person wrote on X (formerly Twitter) ... "Finding out Morgan Wallen cut his hair off just ruined my night."
Another said, "Morgan Wallen cut his hair I can't speak for 5 to 7 business days."
