Wiz Khalifa has done it again. The Pittsburgh rapper has earned another platinum plaque, this time for the success of his second single, "Roll Up."

"As of today, ROLL UP has become another Platinum selling song for @realwizkhalifa. Congrats to the whole team!," tweeted Benjy Grinberg, the President of Rostrum Records. Grinberg was instrumental in helping Wiz launch his rap career.

"Roll Up" follows Wiz's first hit single "Black and Yellow," which was certified double platinum back in February. Both singles are featured on Wiz's debut album, Rolling Papers.
