This picture of Calvin Harris will make you sweat

Crikey, Calvin!

Earlier this week Calvin posted a picture on Instagram to wish his manager happy birthday. It's causing a massive buzz and you can see why, right?

Looking buff and shapely in a pair of Emporium tighty whiteys, he bares almost everything.

Calvin may have won a moon man at the VMAs for his tune 'This Is What You Came For' with Rihanna, but damn he is the furthest thing from it.
