So THIS is the real reason for the Taylor, Calvin breakup?

TMZ is reporting today that Taylor Swift wrote “This Is What You Came For” for her (then) boyfriend, Calvin Harris. They decided to not record it together because they didn’t want the focus taken away from the song itself. He went on to record it with Rihanna.  Taylor has rights to the song and used a fake name “Nils Sjoberg” on the credits.

She felt hurt when he was asked about collaborating with her and he responded, “You know we haven’t even spoken about it. I can’t see it happening though.”

It seems like she didn’t want it to be such a secret or big deal – she just didn’t want to do the vocals on the song with him and cause a fuss.

What a mess. You can read more about it here!

Here’s the song in question…
