Calvin Harris shared a hilarious throwback picture of himself on Instagram on Tuesday, joking that he and his friend look "f*cking fantastic." In the 2002 photo, Calvin is wearing a striped polo, and with his hair dark and long, he's almost unrecognisable. It's true that Calvin's had quite the transformation over the years, and now the superhot star regularly shows off his abs in selfies and underwear ads. Recently, he opened up about Taylor Swift and their relationship, saying she checks boxes he "didn't even know existed," adding, "It's really ridiculous . . . She's generally an incredible cook and human being." Check out Calvin and Taylor's cutest moments, and then see her best moments of the year so far.
