Nick Grimshaw, aka Grimmy, is a British TV and radio presenter and September 24 marks his first day as the new host of 'The Radio 1 Breakfast Show' on BBC Radio 1. One Direction's Harry Styles and Nick are good friends and Harry wants him to know that he supports his latest career move. What better way to show your support than scaring your friend half to death at four in the morning in a #TeamGrimmy t-shirt?

Check out the hilarious clip of Harry Styles (with an adorable new hairdo) waking up Nick Grimshaw below:
