Rich The Kid to Lil Uzi Vert, 'F*** that N****'

Rich the Kid took a big shot at his former friend and current enemy Lil Uzi Vert, telling the crowd at his album release party ... "F*** that N**** Uzi!"

Rich was celebrating the release of his debut album, "The World is Yours" at a Social Group Party at OHM Nightclub in Hollywood, when he unleashed on Uzi.

The beef started when Uzi took a hard pass when he was asked to join Rich the Kid's record label, Rich Forever.
