You'll probably be aware of the shitstorm of drama surrounding Taylor Swift over the past few months.
But if we rewind to a time before Hiddleswift had ever come into the public's consciousness, there was a period of 15 months where Tayvin was a thing.
It was only back in May, but it feels like 500 years ago at this point.
And while they split on what seemed to be fairly mutual terms, things soon turned pretty sour.
Calvin appeared to begin shading Taylor on social media.
And as the drama with Kimye came close to unfolding, Taylor's camp released the shocking confirmation that she had written Calvin's latest smash hit, "This Is What You Came For".
He lost his shit and went on a Twitter rant about the whole thing, and JFC was it dramatic.
Well, last week, after news of Taylor's relationship with Tom Hiddleston ending broke, Calvin appeared to try to make amends.
Speaking to GQ magazine, Calvin revealed he regretted how things had gone down between him and Taylor. He said:
The aftermath of our relationship was way more heavily publicised than the relationship itself. When we were together, we were very careful for it not to be a media circus. But when it ended, all hell broke lose. Now I see that Twitter thing as a result of me succumbing to pressure. It took me a minute to realise that none of that matters.
