Taylor’s rep spoke to PEOPLE this week and revealed it was actually the “Bad Blood” megastar who penned the song under the alias Nils Sjoberg. After throwing her man a major bone, Taylor felt slighted when he went on record to say he can’t imagine working with her, according to TMZ.
The site reports:
During their relationship, Taylor wrote the song, sat down at a piano and did a demo into her iPhone. She sent it to Calvin, who loved it. They both went into a studio and did a full demo with Taylor on vocals and Calvin doing the beat. They both knew the song would be a hit, but Taylor wrote it for Calvin and both agreed it was a bad idea to let the world know they collaborated as a couple … it would overshadow the song. So Taylor, who kept the publishing rights, used the pseudonym Nils Sjoberg on the credits.
Things were all good until the song dropped and Calvin said he “can’t see” himself collaborating with his girlfriend, the report argues:
Fast forward to April 29th. Calvin released the song with Rihanna and it became an instant hit. It’s been at #1 or #2 on the Dance/Electronic chart for 9 weeks, and is #5 on the Billboard 100. The problem in the relationship came the day the song was released. Calvin appeared on Ryan Seacrest’s radio show and Ryan asked, “Will you do a collaboration with your girlfriend?” Calvin responded, “You know we haven’t even spoken about it. I can’t see it happening though.”
After Taylor’s rep spilled the beans, Calvin responded in a seething rant that confirms Taylor wrote the song. He does not, however, touch on the Ryan Seacrest interview in question:
Looks like bygones will not be bygones. And yes, Calvin just confirmed that Taylor hates Katy Perry.
