Rap fans have been talking about Kendrick Lamar and J. Cole's promised collaborative project for years, and just when it seemed all hope was lost for the album, some major hints have arrived. Yesterday, K.Dot and Cole remixed one another's songs for Black Friday, and right at the end of his track, Cole shared a vague promise: 

"When you and K. Dot shit dropping? / Bitch never, they can’t handle two black niggas this clever / But this February, bet shit get scary when I fuck around and drop..."

He trails off before we get to hear what he's actually talking about, but later on, Kendrick Lamar's sister Kayla Duckworth took to Instagram and rave about the records -- giving us an interesting tidbit of info.

"Collab drop #Feb16 so be on the look out for that as well," she wrote, which the sleuths at KTT and Reddit managed to screencap before she deleted it shortly thereafter.

So there you have it. It's not definitive evidence that a collab project is coming our way, but it's certainly a good sign something big is in the works. Check out Kayla's edited Instagram post below, and the screencap in the gallery above.
