On the heels of his Bud Light Dive Bar Tour show, Post Malone stuck around NYC and popped up as a special guest on the Tuesday night (Aug. 6) episode of The Tonight Show Starring Jimmy Fallon. Posty joined his pal to perform a Irish folk song and play beer pong with the late night host, in addition to previewing a snippet to his forthcoming single "Circles."

After enjoying a pint and performing "Seven Drunk Nights" together, the duo hit the beer pong table, where Malone ended up claiming victory. Malone detailed that the drinking game is a staple of the backstage action at his concerts, along with listening to a ton of Shania Twain music and eating plenty of gummy bears.

The 24-year-old also gave a sneak preview to "Circles," which will land on his next album coming out in September. "Run away, but we're running in circles," he crooned over the heavy bass. "On this next album, we're doing a lot of cool, very fresh type of stuff," Malone added.
