Post Malone and Morgan Wallen are joining forces again, on a new song called "I Ain't Comin' Back." After the success of their smash hit "I Had Some Help," the two stars are back in the studio again, but this time it's for Wallen's new album I'm the Problem. Their first duet was a part of Malone's project, F-1 Trillion.

Could Morgan Wallen and Post Malone have hot summer song up their sleeves, repeating the success of last year's "I Had Some Help"? Possibly! The two announced Tuesday (April 15) that they are set to release a new song titled "I Ain't Comin' Back" on Friday (April 18).
