Music's latest and greatest IT couple might've just called it quits. People reports that Taylor Swift and Calvin Harris have broken up after a 15-month relationship. An insider allegedly told the publication, "There was no drama. Things just don't work out sometimes."

In March of this year the too-cute couple celebrated their one-year anniversary with cakes and lockets (it's almost too sweet). A month later Swift spent much of her iHeartRadio Awards acceptance speech talking about how much she loves Harris. It's safe to say love is dead now.

Hopefully the reports are wrong and our favorite blondes are still together. It seems like it would be an especially bad month for Harris, who was in a car crash less than two weeks ago!

For now, take our ultimate Taylor Swift fan quiz. Then revisit this original Fuse interview with Harris, where he talks about collaborating with the always fabulous Rihanna, below.
