Calvin Harris has a message for ex-girlfriend Taylor Swift: Thank you!

The Scottish DJ took to Twitter on Friday to thank Swift and Rihanna for their contributions to his hit single “This Is What You Came For,” which went double platinum in the U.K. recently. “I am blessed to work with incredible artists @rihanna @taylorswift13 thank you!!!” Harris, 32, tweeted.

Swift and Harris’ sudden split in early June may have been due to their musical collaboration. The singer originally wrote the lyrics to “This Is What You Came For” under the pseudonym Nils Sjöberg while dating Harris. A month following their breakup, Swift’s rep confirmed exclusively to PEOPLE that she was, in fact, the song’s writer.

After Swift’s rep confirmed she wrote the song, Harris lashed out at the singer on Twitter. “And she sings on a little bit of it too. Amazing lyrics writer and she smashed it as usual,” he wrote. “I wrote the music, produced the song, arranged it and cut the vocals though. And initially she wanted it kept secret, hence the pseudonym … Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though.”

It appears the exes are on more friendly terms.

In September, Swift was spotted singing along to “This Is What You Came For” at squad member Gigi Hadid‘s Tommy Hilfiger collaboration show during New York Fashion Week. Then she performed the single at Circuit of The Americas’ Formula One Weekend in Austin, Texas in October, one month since ending her high-profile romance with Tom Hiddleston.
