Future previously mentioned this collaboration while promoting Honest, although it didn't end up making the album's final cut. It was just one of many tracks that didn't make Honest, as the rapper said recently he plans on putting some of his leftovers records on a second album, to also drop in 2014.
Whether or not "Rockstar" will appear on his next LP remains to be seen, but today we have the tagged up version of the previously unheard collaboration, thanks to XXL.
The cut has production from DJ Clue, who samples George Michael's "Careless Whisper" (and apparently the sample clearance issue was the reason it didn't make Honest).
A nigga talk slick I'ma get Stun on it
A phone call might get a big gun on it
Who was on it?
Ain't a bitch in the game that'll do what I does on it
