Justin Bieber has been roped in by Calvin Klein to promote its underwear range and the singer has already shot a campaign for the brand.

With this deal, the 20-year-old joins the ranks of supermodels Kate Moss and Lara Stone who have modeled for CK earlier.

Although it's not known how much Bieber charged for the campaign, Moss's first CK contract was worth a reported $1.2 million (Dh4.40 million) - later rising to $4 million, dailymail.co.uk reports.

"Justin has shot for Calvin Klein, we hope the results will be released later this year," said a source from the brand, according to E! Online.

Just last week, Bieber posted a photo of his tattooed body in a Calvin Klein underwear. He was also seen wearing the brand as he hiked up the Runyon Canyon in California and then arrived home in Los Angeles.

In April, it was rumored he would appear in a campaign with Kendall Jenner. The rumors started making the rounds when both stars shared pictures where they are seen wearing Calvin Klein underwear. Jenner took to her Instagram account to share a picture of herself wearing a pair of shaggy jeans that displayed her Calvin Klein underwear teamed with the brand's bra.

"Morning! just going to hang out in #MyCalvins alllll day! ... thank you @calvinklein for my little gifts," wrote Jenner on her Instagram account.

A few days later, Bieber also shared a picture where he was seen displaying his Calvin Klein underwear.

While the rumors are still making it's rounds, an E!Online report said that the news as not true.

"As a policy we don't comment on rumors," a Calvin Klein's spokesperson told the tabloid when asked to confirm about the speculation at that time.

Earlier this year, model Christy Turlington also reprised her role as the face of Calvin Klein. She featured in the brand's latest fragrance ad campaign with her husband Edward Burns.

She first bagged the role of the face of Calvin Klein's fragrance line 'Eternity' in 1988. Even though Turlington remained the face of the brand's fragrance line till 2007, her most iconic photo shoot for 'Eternity' came in 1995. Last month, the actress gave her fans an opportunity to revisit those glorious days by posting a picture of that photo shoot on Instagram.

Turlington is also the founder of the maternal health advocacy campaign "Every Mother Counts." As a welcome back gift, Calvin Klein has announced that it will donate 100 percent of the proceeds from the U.S. sales of Eternity Calvin Klein's 25th Anniversary Edition bottles for one week (starting May 30, 2014) to the charity, according to E! Online.
