T.I.’s working relationship with Pharrell dates back to Tip’s I’m Serious days; for those of you not hip to the game, that’s 2001. The two have remained close and any time T.I.’s got a new album cooking you better believe Pharrell will be there either providing Tip with the hook, the chorus, a verse, or production. Hell, sometimes he’ll gift Tip with all four! And for T.I.’s forthcoming studio album Paperwork the two reunite once again. Pharrell joins Tip for “Paperwork” and it’s a scorcher. Listen after the jump.
