Calvin Harris has reportedly refused to collaborate with his girlfriend Taylor Swift amid concerns it will ruin their relationship.
The Scottish DJ-turned-superproducer has worked with some of the music world's biggest stars, including Rihanna and Ellie Goulding, but he is allegedly hesitant to work with Taylor after collaborating with his former girlfriend Rita Ora led to the bitter demise of their romance.
The couple split in 2014 after hitting the studio together to work on a number of songs, including I Will Never Let You Down, and after the break-up, Harris reportedly imposed a ban on Ora performing the track.
Now sources tell British newspaper The Sun that the DJ's team proposed the idea of working on a track with Bad Blood hitmaker Swift, but Harris was not interested.
"Calvin's next single is ready but the label is keen for him to get a big female US star to collaborate on it," the insider told the newspaper. "They floated the idea of him working with Taylor but he politely declined it."
