He's not very shy clearly.

Calvin Harris left little to the imagination with his latest Instagram post and sent his fans in a frenzy. He was wishing his manager a happy birthday and instead of just posting a normal picture of the two of them, he uploaded a picture of himself in boxers alongside the birthday boy. The slightly odd thing is that it looks like neither of them were even ready for the photo with his manager looking like he is about to speak and Calvin is standing awkwardly. But all that aside, he still felt like it was the best photo to use for the birthday post. He shared the picture with the caption, "Happy birthday to my manager @gillespiemark I love u."

As you can imagine, with a half naked photo of the Scottish DJ, the internet responded accordingly with fans freaking out over the photo. One person said, "Looking good as ever damn 4 letters DAMN" and another commented, "Omg Calvin! You are such a handsome man! I'm literally in love with you." Some others, though, were not as impressed with one person adding, "This is the most awkward photo I've ever seen. Seriously weird," and another saying, "please stop standing around in your underwear." And they're not exactly wrong - he's very fond of the old underwear shots following his sponsorship with Emporio Armani.

On tour but also training for next Armani shoot! Staying in a gym routine while on the road is tricky, but as long as you don't drink, eat well, sleep enough and take one of those mad little ab rollers with u everywhere you'll be good A photo posted by Calvin Harris (@calvinharris) on Mar 23, 2015 at 4:27pm PDT
