The Swedish communications manager Nils Sjöberg had no idea he was about to become famous. Or at least, no idea that his name was about to become famous. But in late June, when the Swedish morning show “Nyhetsmorgon” declared “This Is What You Came For” the song of the summer — and mentioned that it was co-written by Calvin Harris and Nils Sjöberg — the tweets started rolling in.

“I thought it was some kind of spam,” Sjöberg said by email from the countryside, where he’s on vacation. “Discussions started on Twitter and Tumblr if the whole thing was a PR stunt, if I was a real person (!) and if I had written the song with Calvin Harris for real.”

He had not.

It turns out that, in addition to 110 real Nils Sjöbergs living in Sweden (according to Sjöberg), there’s (at least) one fake Nils Sjöberg who lives in the U.S. Today we found out that her real name is Taylor Swift, and she adopted the pseudonym to help Harris, her boyfriend at the time, write his summer hit.

Since then, the pair have split and Swift has started dating — or doing something that looks sort of like dating — Tom Hiddleston. The two have spent the last couple weeks on a vacation tour that’s so thoroughly documented, the paparazzi appear to have been cordially invited.

TMZ broke the news that Sjöberg was in fact Swift with the pointed statement that “Taylor Swift really is the creative brains behind Calvin Harris’ monster hit.” Harris wasn’t entirely enthusiastic about that characterization, so he took to Twitter to air his grievances.

What a mess.

At least the real Sjöberg is taking it all in stride. He already had a Tumblr where he asked people to send him their first world problems, which he turned into drawings. This situation has given him fodder for his own.

“Today, my Twitter and Tumblr has more or less exploded with tweets, reblogs and continuing discussions,” Sjöberg said. He hasn’t responded to all of the message yet, because he’s on vacation. And for people who aren’t Taylor Swift, that means taking a break.
