Royce Da 5'9" has put an end to the rumors that Lupe Fiasco cold be joining Slaughterhouse to replace retired rapper, Joe Budden -- but Royce says that nobody could take Budden's place.

"It will never happen. Nobody can replace Joe. Nobody can replace anybody from Slaughterhouse. If Lupe was to take Joe's spot and it'd be me, Lupe, Joell, and Krook, then it'd just be a different group. It wouldn't be Slaughterhouse. It would have to be called something else and that's certainly not taking anything away from Lupe. If anything, that's elevating Lupe to where he should be. He's no group replacement guy. He's great. He's not just an emcee, he's a master," he told HipHopDX.

But his dismissal has nothing to do with Lupe's skill set as a rapper:

"It's more to it than that. It's not just lyrically what makes Slaughterhouse click. It's something about the dynamic of us four people. There's even still things about that dynamic that people are drawn to that I still haven't figured out and I'm one of the people who was instrumental in pushing for us to be a group... It's something about us four that people just like."
