Rihanna Just Entered The Calvin Harris And Taylor Swift Breakup Theory

OK guys, no big deal or anything, but we think we've found the REAL reason why Calvin Harris and Taylor Swift broke up.

It's a bit of a truth bomb, so I hope you're ready for this. Ready? OK.

So apparently Tay secretly wrote Calvin's massive banger "This Is What You Came For" and their relationship hit a major rocky patch after it was released, which ultimately led to their sad demise, according to TMZ.

Yeah. At the time, she reportedly busted out the tune on the piano and sent an iPhone clip to her boyfriend. He loved it, and shortly after it was released with Rihanna. Taylor reportedly kept publishing rights, but is rumored the have used the pseudonym Nils Sjoberg on the credits.

That was all dandy. But a source told TMZ the tipping point came when Calvin was interviewed and asked about a potential collaboration with his girlfriend. He said, "You know we haven't even spoken about it. I can't see it happening though."

Taylor reportedly took this to heart. So maybe we've been going too hard on our old friend Tay. Because, if this really IS the case, she would have the right to stop Calvin from performing this massive hit, just like he did for then girlfriend Rita Ora -- remember that!?

Meanwhile, there's a lot of weird stuff going on with Taylor and Tom Hiddleston. Fan theories suggest the whole thing is fake. People are throwing out random reasons why the couple are actually together, like the love display is just for a music video. If that's the case, it's been going on for so long that I hope it's the most elaborate piece of video genius I've ever seen.
