Pharrell recently shared a photo of him in the studio with T.I. and Kendrick Lamar. It's not known what the trio of hip hop heavy hitters are working on; it could be Tip's next album, the Grand Hustle compilation album, or possibly even Pharrell's solo album
He was also in the lab with Kid Ink in L.A. recently.
On a different note, check out some pics of Pharrell hanging out in Austin for SXSW.
