When Calvin Harris stripped down and sent Internet into frenzy!

Calvin Harris took to Instagram to post a photo in his undies — and clearly sent the Internet into a frenzy. The currently single DJ posted a photo on Tuesday to wish his manager, Mark Gillespie, for his birthday. He captioned the photo, “Happy birthday to my manager @gillespiemark I love u.” The Under Control singer and ex-boyfriend of Taylor Swift, also took the opportunity to show off his toned physique.

In May, he posted a now-deleted shirtless photo on Instagram showing off his body. A month later the DJ proved he was putting in some serious overtime at the gym when a friend of his posted photos of Harris posing in gym-wear.
