Dj Calvin Harris has slammed accusations he uses a ghost producer on his tracks.
The Scottish star has been hit with online speculation that someone else is behind his hits, which include four number one singles and two chart-topping albums in the U.K.
Harris, who was named the world's highest paid Dj by Forbes last year (13), has now taken to Twitter.com to insist his success is all down to his own hard work.
He writes, "Honest to God nothing more annoying than people telling me i have a ghost producer smh (shaking my head)... Working on this 16 years to be told some old guy in a secret studio must be making my records for me... Producing is something that i am good at. I also write songs. Lyrics. And i mix them. & sometimes i sing them. F**k ye (sic)."
