Post Malone and 21 Savage's chart-topping collaboration "Rockstar" has already gone platinum.

The Recording Industry Association of America (RIAA) has confirmed the track, which was released less than two months ago, has surpassed the million units mark, as of Oct. 27.

The news comes as "Rockstar" is currently enjoying its fourth consecutive week at No. 1 on Billboard's Hot 100 song chart in the U.S. Malone's debut album Stoney, which arrived last December, has also been certified double-platinum.

To celebrate, Post Malone has released an "unofficial" video for "Rockstar," with an official clip expected soon.
