Jermaine Dupri says super producer Jazze Pha is WRONG -- he never signed on to participate in the Super Bowl halftime show ... but it has nothing to do with Colin Kaepernick.
Pha is a producing legend in ATL and he's super plugged in -- so, when he told us Dupri was involved in the show, it sounded legit.
But, Dupri says Pha's just wrong -- and when we started questioning Jermaine he told us point blank, "You think I'm saying no because it's a secret? No means no."
Dupri says he's not boycotting the NFL over Kaepernick -- he says the NFL simply never called when they were putting the show together and he REFUSES to be considered an afterthought.
"It should have been a decision that they made at the beginning. I'm not something that you call later on in life."
So, Dupri is out -- but Maroon 5, Travis Scott, Big Boi from Outkast and Gladys Knight are all in to perform on Feb. 3.
As we previously reported, some huge stars like Common have called for the performers to back out over the way the league has treated Kaepernick, but that's just not happening at this point.
