Morgan Wallen had a hometown surprise for Pittsburgh fans during his concert Thursday night ... Wiz Khalifa!
WIZ & WALLEN
The concert was packed when Wiz, who grew up in Pittsburgh, appeared on stage and sang "Black and Yellow," as fans went wild. The optics were pretty spectacular ... flames shooting up in the air with yellow lights surrounding the venue.
Morgan and Wiz embraced as they left the stage. Seems Wiz is a Morgan fan .
