VIDEO : Apparently a Calvin Harris and Taylor Swift Collaboration is Not Happening Any Time Soon

Calvin Harris and Taylor Swift may be one of the highest-earning celebrity couples in the world, but that doesn?t mean a musical collaboration will ever happen. The ?How Deep Is Your Love? DJ reportedly refuses to work with his famous girlfriend because he worries it could jeopardize their relationship. ?Calvin?s next single is ready but the label is keen for him to get a big female U.S. star to collaborate on it,? an insides tells British newspaper, The Sun. The former couple split in 2014 after hitting the studio together to work on a number of songs, including ?I Will Never Let You Down?.
