As the feud between Treach and Funkmaster Flex over the honor of the late, great Tupac Shakur continues to escalate, the Naughty by Nature front man decides to verbally air him out on stage.

Naughty by Nature performed at a concert on Friday night in Worcester, MA. During a brief interlude, a classic photo of Pac appeared on screen and Treach spoke to the roudy crowd about his beef with the longtime Hot 97 DJ.

“Flex dissed my brother Tupac and he ain’t here to defend himself, but I am,” Treach announced to the crowd.

After taking a shot in honor of his longtime friend, Treach proceeded to pour some of the liquor onto the tattoo of his portrait and said, “When I drink, you drink. When I smoke, you smoke. When I fuck, you fuck. When I ride on that bitch ass ni**a Funkmaster Flex, you ride on that bitch ass ni**a Funkmaster Flex.

In the same week, Treach dropped a vicious diss record towards Funk Flex after he once again dragged the “Dear Mama” rapper’s name through the mud and claimed that he lied on Biggie, resulting in his death six months after Tupac’s.
