Well it looks like the conspiracy theorists were right!

Not two weeks ago, we covered a story that Calvin Harris and Taylor Swift fans were absolutely convinced that Swift had a small vocal part in Harris and Rihanna’s latest hit, “This Is What You Came For.” Another tangentially related theory supposed that Swift actually had writing credits on the song under a pseudonym, Nils Sjöberg.

A rep for Swift has confirmed that she has a writing credit in the song, and Calvin separately confirmed that she sang on it, as well.
