DJ Calvin Harris is reportedly in no mood to collaborate with his girlfriend Taylor Swift.
The 32-year-old Scottish record producer politely denied the offer to join hands with the Grammy-winning songstress, reported Aceshowbiz.
"Calvin's next single is ready but the label is keen for him to get a big female US star to collaborate on it. They floated the idea of him working with Taylor but he politely declined it.
"Calvin has seen how sour things can turn when working with someone he's dating. He is very serious about Taylor and doesn't want to rock the boat. He's smitten," a source said.
The EDM star produced some songs for Rita Ora when they were dating. After they broke up, he banned her from releasing those tracks.
