"And she sings on a little bit of it too. Amazing lyrics writer and she smashed it as usual," he wrote on Twitter. "I wrote the music, produced the song, arranged it and cut the vocals though. And initially she want it kept secret, hence the pseudonym."

Calvin Harris continued, saying it is "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."
