Kylie Jenner hides behind security blanket in Calvin Klein ad — and Twitter has theories why

Calvin Klein launched a new global campaign on Monday morning featuring the Kardashian-Jenner clan, and a rare appearance from Kylie Jenner. The youngest of the five sisters is reportedly pregnant, and has avoided the public eye for nearly five months. Although fans are excited to see that she’s re-emerged, they have some theories about the photos.

Following the general vibe of most of the brand’s advertisements over the past few decades, the campaign photos have the family wearing nothing but their undergarments — with the exception of 20-year-old Jenner. The lipstick-mogul stays covered up under a blanket, while her sisters flash their abs. Because of this modest pose people on Twitter have further evidence to believe that Kylie’s expecting her first child.

While the images released are for the Calvin Klein brand at large — including both their underwear and jeans — it’s clear that Kylie is the only sister not featured in just a pair of undies. She also takes a backseat to her sisters, with just one photo showing her in the front of the pack and in that she’s wearing a full-coverage black button-down shirt with the blanket still in hand.

The confusing photos are drawing heightened attention to Kylie’s abdominal region, prompting social media users to believe that she must be hiding something.

But what about the confirmed-pregnant sister, Khloe?

After announcing that she’s officially six-months pregnant in early January, it seems that Khloe is earlier on in her pregnancy than Kylie allegedly is. At the time that the campaign photos were taken, the Revenge Body host was likely not showing enough to deserve a security blanket.

All in all, fans are excited about the photos, and seeing all five sisters back together again. But the campaign is giving just a little more hope to the idea that there might be another Kardashian-Jenner grandchild on the way.
