Kendall Jenner shared a new picture on Instagram of her lounging on a sofa in her underwear. The photograph is actually a part of a Calvin Klein campaign that she was a part of, and it marks the 50th anniversary of the company.

Jenner shared a picture of her wearing a new line of Calvin Klein underwear on her Instagram page. The new line of clothes have the words CK50 on them, which signifies that it is a limited edition that marks the 50th anniversary of the company.

The model has a partnership with the company for the new campaign, which she also announced in the post. She also tagged the company and revealed the campaign’s hashtags as #mycalvins and #ck50.

Calvin Klein made a video for the campaign that Jenner recently shared on her Instagram page. Apart from the model, the video includes Justin Bieber and his wife Hailey Baldwin, who are featured prominently in it.

The video shows a shirt-less Bieber sitting on the bed with Baldwin, as they both watch the rocket launch that put the first man on the moon. With the EMF song “You’re Unbelievable” playing in the background, the couple can be seen dancing and acting playful with each other. There is also a shot of the singer carrying his wife in his arms and giving her a kiss.

Jenner appears in three settings in the campaign. She is first in a car, exploring the city as it makes its way through the city, and she later arrives at a venue where everyone is wearing Calvin Klein clothes. Towards the end, she is seen lounging on a sofa in the company’s underwear, and checking out her cell phone.

The phone Jenner uses is a flip phone, and as she leaves the room, the screen shows a blurry selfie of the model. The video has a retro feel to it, which highlights Calvin Klein’s 50-year history.
