Canadian singer Justin Bieber and Dutch model Lara Stone co-star in the latest campaign for Calvin Klein's Jeans and Underwear lines.

Calvin Klein's latest campaign sees the return of Dutch supermodel Lara Stone, who has worked extensively for the brand, alongside Platinum-selling pop phenomenon Justin Bieber.

The Spring 2015 Calvin Klein Jeans and Calvin Klein Underwear global campaign, which was shot by fashion photographers Mert Alas & Marcus Piggott in New York City, shows off the brand's key jeans and underwear styles.

"I have been a longtime fan of the brand and have worn their jeans and underwear for a while, so this is kind of a dream come true," said Bieber.

The pop meets fashion connection in the pictures goes back to one of the brand's earliest campaigns featuring Mark Wahlberg and Kate Moss. Other musicians dressed by Calvin Klein include Kanye West, Drake and Taylor Swift.

"Given my on-going relationship with the house, this shoot reunited me with my Calvin Klein family – and it was really fun working with Justin," added Stone. "We had a great time on set and we had a lot of fun shooting the campaign. I think the shoot really captured the energy of the Calvin Klein brand."

The new campaign will get a global roll-out in 20 countries with new experiential marketing also in the works in time to arrive with March 2015 magazine issues.
