Kendall Jenner has been a fan of Calvin Klein underwear for at least a year. She has posted pictures of herself wearing the brand on her Instagram page on several occasions, and now it appears that she will become a spokeswoman for the company, according to sources.

Sources tell Page Six that Jenner has signed on to be the face of Calvin Klein underwear. That would mean more than just self-taken pictures of her in Calvin Klein underwear for her Instagram. It would mean professionally done photoshoots.

Jenner has been active modeling this week for Paris Fashion Week. She has been walking the runways for Chanel and Balmain, so this would be a good time for her to sign on with Calvin Klein.

Similar posts by Justin Bieber were made on his Instagram shortly before he became a spokesman for Calvin Klein Jeans. Jenner's posts of her wearing the Calvin Klein underwear might be a clue that she is joining Bieber in officially representing the company.

The role that Jenner is likely to take on has not been confirmed by Calvin Klein yet, but sources tell Page Six that Calvin Klein's next underwear ad campaign will feature Jenner in a big way.

Calvin Klein probably noticed that Jenner has almost 21 million followers and, if she already loves their underwear, they should take advantage of that and hire her to model for them.

Jenner already is a spokeswoman for Estee Lauder. If she signs on with Calvin Klein underwear like expected, she will join past spokeswomen Brooke Shields and Kate Moss, who have also represented Calvin Klein.

In a recent interview with Latina model Joan Smalls for Estee Lauder, Jenner talks about how she found out she would be the face of the beauty brand.

" I was so excited," she said. "I found out backstage in Paris and they told me I couldn't say anything. So I saw the text and I was like, "Oh my God! I have to keep this to myself." When I got to my room I started freaking out."
