Los Angeles, Nov 5 (IANS): Scottish DJ Calvin Harris says he is "blessed" to work with his former girlfriend Taylor Swift.

Harris took to Twitter on Friday to thank Swift and singer Rihanna for their contributions to his hit single "This is what you came for", reports people.com.

"I'm blessed to work with incredible artists Rihanna, Taylor Swift, thank you", he tweeted.

Swift 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 representative confirmed that she was the song's writer.

After the confirmation, Harris lashed out at the singer on the micro-blogging website and posted: "And she sings on a little bit of it too. Amazing lyrics writer and she smashed it as usual. 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," Harris added.
