Justin Bieber is now making the headlines as a new model for Calvin Klein's #mycalvins campaign.

The 20-year-old posed for the underwear company in nothing but boxers, showing off his tattoos and abs.

According to Hollywood Reporter, Bieber may have caught the attention of the Calvin Klein brand during the Fashion Rocks in September, where he stripped down to his red-and-black CK boxers besides Lara Stone, who is also in the #mycalvins campaign.

The "Baby" singer also posted a tweet saying that he is now officially "part of the legacy" with the hashtags #newfaceofcalvinklein and #mycalvins.

Bieber, born in London, Ontario, also posted a photo on Facebook with the caption "It begins."

Even before, the American fashion house used to feature music-related celebrities in their ad campaigns.

According to Yahoo News, Nick Jonas posed for the Manhattan-based firm in a spread for the Flaunt magazine.

Also, decades ago, Mark Wahlberg also posed for Calvin Klein. The 43-year-old Hollywood actor posed only wearing a white boxer, also showing his abs in the campaign years ago. Some ads also featured "The Gambler" star with English model Kate Moss.

The Canadian singer and songwriter was famous for his hit singles "One Time," "Never Say Never," and "Boyfriend" among others.
