SCOTTISH superstar DJ Calvin Harris has revealed that his younger teenage self would have no conception of how he lives now.

The Dumfries-born music legend, who is worth almost £50million having collaborated with singers Rihanna, Ellie Goulding and Dizzee Rascal, is rumoured to earn almost £300,000 for a gig in a deal signed with Hakkasan nightclub in Las Vegas.

In his first interview in four years, as he fronts a new advertising campaign for Armani, Harris has said when he lived in Glasgow at the start of his career, Harris would never have dreamed of shopping in the Armani store in the Merchant City.

"I never went up to that end of town. It was dead fancy," he said.

The 31-year-old DJ, songwriter and singer, who released his first album I Created Disco in 2007, now owns a 10-bedroom home worth $15m in Los Angeles and is regularly flown around in private jets.

It is a far cry from his modest upbringing, when he was known as Adam Wiles, and the family house "was in a development where all the houses look exactly the same, called Georgetown".

The modelling assignment with Armani lifts Harris into the realms of David Beckham and Cristiano Ronaldo. He doesn't smoke or take drugs and hasn't drunk alcohol for nearly a year. He said he spent four months working out in preparation for the photo shoot and he was actually the one who suggested getting his kit off.

"I just feel like if you're going to do it, you may as well make the biggest impact you can," he said.

"There's no way that situation can be made comfortable. There just isn't. They just tell you how to pull and adjust them.

"I'm well happy I did it. You wouldn't expect it al all, would you?"

Harris said he stopped giving interviews in 2011 and refused to comment on his break-up with pop star Rita Ora or current links to 21-year-old model Aarika Wol, who starred in his video for Blame.

Despite the bright lights of LA and Las Vegas, Harris said one of his finest moments was headlining at last summer's T in the Park and being introduced on stage by Hollywood star Will Smith.

Smith had contacted Harris about coming to a couple of his shows and the DJ suggested he wait until the Balado music festival.

"As he walked into the spotlight, you could hear the ripple through the crowd. That was the moment," said Harris.
