Lupe Fiasco casts doubt on his Kanye and Pharrell supergroup

Child Rebel Soldier, the hip-hop supergroup featuring Lupe Fiasco, Kanye West and Pharrell Williams, may be over.

The group have released two tracks 'Us Placers' on Kanye's 'Can't Tell Me Nothing' mixtape in 2007, and 'Don't Stop' which appeared as part of Kanye's G.O.O.D. Fridays releases prior to My Beautiful Dark Twisted Fantasy last year.

Now Lupe Fiasco tells AllHipHop that a full Child Rebel Soldier album may never happen.

"Everybody has their different approaches," he revealed. "Do you want a CRS album or do you want a 'Friend of the People' mixtape or do you want a Food and Liquor 2 or do you want… It's like, you know, you can't do all of it."

"And then with CRS I have to get Pharrell on the same page and get Kanye on the same page – is it something that we even still want to do, you know? It was something that we maybe thought about doing three or four years ago. Three or four years later, is that something that we still want to do?"

And even if they were still into the idea, the logistics might make it impossible.

He continued, "There's three other people that's involved; three different record labels; three different kinds of systems and management and all this other kind of stuff involved. So, creatively I'm always down to collaborate but, this particular thing, I don't know."
