Travel to Timbuktoo and we bet you still won't be able to avoid gossip about Taylor Swift.

As such, we may as well tell you the latest nugget.

The latest report fresh out of Tinsel Town suggests that Taylor Swift and Calvin Harris's break up may have been down to none other than Harris' two-time collaborator Rihanna.

But before you start trolling Riri for breaking up Tayvin, let us explain.

Rumour has it that Swift actually penned Calvin and Rihanna's current hit This Is What You Came For under the pseudonym Nils Sjoberg.

A side note: The theory that Swift is actually Sjoberg is nothing new. 

Since the track's release there has been much speculation, with many fans believing Swift's vocals can actually be heard on certain parts of the track. 

Also of note is the fact that the original Wikipedia entry for the song, apparently, listed Harris and Swift as writers, before being edited to say Harris and 'Nils Sjoberg' instead.

Add to that the fact that a cursory Google of the name brings up pretty much nothing and no one of note, except a Swedish poet who apparently finds it amusing that people think he might actually be Taylor Swift.

An Instagram picture of Swift wearing a bomber jacket featuring the single's artwork is also one of the very few Calvin-related pics that survived her post-break-up cull...

Anyway, according to TMZ,  after writing and recording a demo of the song, Swift encouraged Harris to instead record it with Rihanna as she feared their then-relationship would overshadow it if it was released with her as the vocalist.

Harris is then said to have 'dissed' Swift publicly on the day of the song's release in April when appearing on Ryan Seacrest's radio show. When asked if he and Taylor would collaborate he said: 'You know we haven't even spoken about it. I can't see it happening though.' Despite the fact Swift had (reportedly) written his new hit.

Rude. The 'diss' was apparently the final nail in the coffin for Tayvin.

Swift has still got the publishing rights though, according to TMZ. Ker-ching.
