Hey, do you know what Calvin Harris looks like when he's only wearing a pair of Emporio Armani boxer briefs?

If you don't, there's a simple way to find out! Just look at Harris' Instagram wishing his manager, Mark Gillepsie, a happy birthday with a photo that's primary purpose is showing off the DJ's toned bod.

Still, the photo is heartbreaking because it proves that Harris and Taylor Swift were truly meant to be. Swift, as you may recall, also loved making other people's birthdays about Calvin Harris.

Here's the photo she selected to wish Karlie Kloss a happy 23rd birthday:

Anyway, Tom Hiddleston's birthday is Feb. 9.
