Post Malone is prepping for the release of his sophomore album Beerbongs & Bentleys with some help from 21 Savage.

Posty, who is currently on the “Stoney Tour” through North America, has reportedly enlisted the ATL rapper for “Rockstar,” the first single from his second full-length album. According to HipHop-N-More, the collaboration is set to drop Sept. 15.

In December, White Iverson previewed “Rockstar” on social media. “Your girlfriend is a groupie,” he sings on the track. “She’s just trying to get in / Saying ‘I’m with the band’ / Now she acting out of pocket, trying to grab up on my pants.”

The Posty and Savage connection could prove to be another Hot 100 smash. Malone currently has the No. 21 record in the country with “Congratulations,” while Savage’s “Bank Account” is No. 12.

Initially due in June, Beerbongs & Bentleys is the follow-up to the platinum Stoney, which spawned several platinum hits, including “Congratulations,” “Go Flex,” and “White Iverson.”
