If you cast your mind back to 2009, you may remember the cute celebrity pairing that was Taylor Lautner and Taylor Swift.
The romance didn't last long, but Taylor's song "Back to December" has since been interpreted to be about the other Taylor.
It features some pretty heartbreaking lyrics:
So this is me swallowing my pride,
Standing in front of you saying, "I'm sorry for that night,"
And I go back to December all the time.
It turns out freedom ain't nothing but missing you.
Wishing I'd realized what I had when you were mine.
I'd go back to December, turn around and make it all right.
I go back to December all the time.
