"Over Now" will be the first time The Weeknd and Calvin Harris have worked on a song together, and will follow on from The Weeknd's posthumous Juice WRLD collaboration "Smile" that dropped earlier this month.
The Weeknd confirmed news of "Over Now" on socials over the weekend (22 August).
Abel Tesfaye, aka The Weeknd, released his latest album After Hours in March.
This year, Calvin Harris has been releasing music under his Love Regenerator moniker. His most recent single was last month's "Live Without Your Love" featuring Steve Lacy.
