HE HAS come a long way since his days as the geeky, baggy-clothed DJ on Dizzee Rascal's Dance Wiv Me video.
Not bad for a normal lad from Dumfries.
Calvin's body tranformation has seen him ditch the straggly bowl haircut, goofy poses and student-like clothes for a more refined, grown-up look.
Also gone is the puppy fat and spotty complexion.
The 31-year-old Feel So Close hit maker reportedly owes his new good looks down to his LA lifestyle, where he has been living since 2012.“The food is fantastic over here”Calvin Harris on his LA lifestyle
Calvin starts the day with a home-cooked breakfast of egg-white omelette, smoked salmon and spinach, before heading to the gym.
"The food is fantastic over here. You can eat healthily, there’s a lot more healthy options than in the UK — that’s a fact," he said.
At the gym Calvin has been seen honing his lust-worthy six-pack by doing private Pilates classes.
"It was hard being the tallest person in class. Especially when you are a teenager. You want to keep your head down. I did anyway," he said.
"When you are a spotty awkward teenager, you don't want people to look at you. It's a self-conscious thing. Everyone looks at you because you are extra gangly.
"It's only in the last five years that I have come to terms with the fact that I am a big tall b******."
One of the biggest difference's to Calvin's new look has been embracing his natural blonde hair in 2012.
"It’s just part of growing up, coming to terms with myself as a human being and not doing that s*** any more. I prefer my more natural look," he said.
"If anyone doesn’t, they’d be preferring something that isn’t actually real — so it’s like you’re preferring an imaginary idea of someone who doesn’t exist. You either like it or you don’t like it."
