Calvin Harris' Shirtless Body Is Hotter Than Ever—See the Photo and Find Out How He's Preparing for New Armani Shoot!

The 31-year-old Scottish "Summer" and "Outside" performer is a spokesmodel for the brand in December and showcased his chiseled body (and bulge) in an underwear campaign this year

Calvin Harris is so ready to strip down once again for Emporior Armani!

The 31-year-old Scottish "Summer" and "Outside" DJ has been working hard to transform his technically good physique into chiseled perfection and resume the role of underwear model hottie.

And it's partially thanks to...ab rollers.

Harris, who is also the highest paid DJ of 2014 with $66 million in annual earnings, according to Forbes, was in December named as a celebrity spokesmodel for Emporio Armani. Harris showcased his ripped body while wearing tight white and black briefs in a spring / summer 2015 ad campaign, released in February.

This week, he posted on his Instagram page a selfie that shows him possibly even more ripped than ever.

"On tour but also training for next Armani shoot!" Harris said.

Photos of Harris at the beach in Malibu, California later that month and a cover of the Sunday Times' Style magazine's March 15, 2015 issue, shot weeks ago, showed his muscle tone to appear less defined.

The singer/DJ has been working hard on his fitness while on tour. He is set to perform at Lollapalooza 2015 in Brazil this weekend and has gigs in Las Vegas throughout April and May.

"Staying in a gym routine while on the road is tricky, but as long as you don't drink, eat well, sleep enough and take one of those mad little ab rollers with u everywhere you'll be good," Harris wrote.
