Kim Kardashian and her sisters (including a suspiciously pregnant Kylie Jenner) pose in their underwear for Calvin Klein

You can always depend on the Kardashian/Jenners to get people talking on an otherwise bland, weekday morning.

Kim Kardashian and her sisters have given everyone something to talk about today, thanks to their new ad campaign for Calvin Klein which sees them posing in their underwear. CK underwear, naturally.

This is actually the first time all five girls have posed together for something that isn’t one of their own projects, which makes this ad campaign pretty special.

Kim, Khloe and Kourtney Kardashian, alongside Kendall and Kylie Jenner, were photographed by Willy Vanderperre for Calvin Klein in a variety of different poses.

However, it’s the poses of a certain Kylie Jenner that have received the most attention, as she continues the “is she pregnant? Isn’t she pregnant?” charade.

In one shot, the 20-year-old’s body is hidden under a blanket, while her sisters are acting as very clever shields in a few others.

Oh, how they like to tease!

All of these pictures are part of Calvin Klein’s ad campaign which focuses on the celebration of family. Willy Vanderperre previously photographed Presley and Kaia Gerber (Cindy Crawford and Rande Gerber’s children) for the same campaign.

And don’t forget to take a look at the video below, which features the Kardashian-Jenner sisters play the always entertaining ‘Never Have I Ever’ game.

It’s definitely well worth a watch!

So what do you make of Kylie’s strategic posing?
