We've heard rumours about a J. Cole and Kendrick Lamar mixtape, and now we get some confirmation from J. Cole that the project is actually happening,

In an interview with Hot 97.5's Bootleg Kev, J. Cole revealed he's started working on it,

"I just started working with Kendrick the other day," he said, "We got it in, finally, again. [It's gonna be an] album, man," 

"We actually worked, bouncing ideas, which was great. The vibe was so good that it was like, man, that’s absolutely gonna happen," he added.

“We got maybe four or five [songs] together."
