From Supreme Clientele's wiki page:
In 2004, Lord Superb, formerly of Raekwon's American Cream Team and a collaborator of Ghostface's, made claims that he had "ghostwritten" the entire album of Supreme Clientele.[3] Superb has admitted to writing Ghostface a verse on the previously unreleased GoodTimes Pt. II. Tony Yayo of G-Unit would later bring the topic back to the surface in 2006,[4] however, in an interview with Rhapsody Music, Ghostface responded with:
"Yeah, I was in Europe when I heard Tony Yayo say that. That’s just nonsense. I still put mad shit out. 'Perb (Superb) is Rae’s (Raekwon) man. He been in the studio a few times while we’re doing shit. He ain’t write shit. All ‘Perb contributed was a couple of lines that you could put in the air. When we write, we all do that. “Say this one right here” or “Put this one right here.” We all catch lines with each other ‘cause you in the studio. You got niggas around you that write. Even if he did write a verse, he could never make an album of mine. He couldn’t make an album, you feel me? I made Supreme Clientele what it is. Those are my stories, based around what they’re based upon. It’s me. I can’t see what songs ‘Perb wrote. He ain’t write "Mighty Healthy" or "One" or "Apollo Kids" or "Cherchez LaGhost" or "Saturday Nite" or "Malcolm".[5]

GFK goes from denying he wrote anything to saying he contributed some lines to saying even if he did write a verse. He either contributed to the album or he didnt.
