The Weeknd - whose real name is Abel Tesfaye - took to Twitter to share some artwork from the track, entitled 'Over Now', and revealed the tune will drop on August 28th.
He wrote: ''over now. friday. @calvinharris (sic)''
Calvin also posted some of the tune's artwork on Instagram, and he wrote: ''Brand new this Friday @theweeknd (sic)''
The announcement appeared to excite a number of his fans, including record producer Afrojack.
He wrote: ''loookibg forward (sic)''
Musician Dillon Francis wrote: ''Wow''
Last week, the pair teased a potential collaboration when they posted an Instagram throwback selfie of themselves drinking together.
They captioned the image: ''don't get too confused. (sic)''
Calvin later shared a clip of 'Over Now' on his Story.
It's thought the pair's upcoming release may well feature on Calvin's next album.
Calvin hasn't released a duet since his hit 'Giant' last year, which featured Rag'n'Bone Man.
What's more, The Weeknd recently teamed up with Doja Cat on a remix of 'Blinding Lights' from his acclaimed LP 'After Hours'.
