Calvin Harris may be pretty cool these days – dating Taylor Swift and fronting a shirtless campaign for Emporio Armani – but he doesn’t mind looking back on his dorkier younger self.

The 31-year-old DJ shared a throwback photo of him on a night out with his friend Irv in 2002, when he was still just a teenager living in Scotland.

The two are in Jumpin Jaks, a night club in Dumfries which closed five years ago, and Calvin sports a striped polo shirt with a T-shirt underneath.

In 2009, when he hit fame with his album Ready For The Weekend, he was still looking pretty geeky.

But in recent years, the star has undergone a transformation, hitting the gym and revamping his wardrobe.

In newly-released photos for an Emporio Armani campaign, Calvin is pictured posing in tight black briefs and showing off his six-pack.

He follows in the footsteps of Cristiano Ronaldo and David Beckham, who have both fronted campaigns for the brand.

The throwback photo should give hope to dorky 18-year-olds everywhere.
