Her pregnant sister Khloe Kardashian bared her bump for the underwear shoot, but Kylie had the covers pulled firmly over her tum
Kylie Jenner ‘s pregnancy is a riddle wrapped in an enigma.
But the reality star sent yet another clear sign she’s up the duff when she posed for a Calvin Klein underwear shoot with her stomach completely hidden.
Her sisters Kendall Jenner and Kim, Khloe and Kourtney Kardashian stripped to their knick nacks for the sexy shoot, which saw the girls lie supine on a duvet cover.
And while all had their stomachs out – including pregnant Khloe – Kylie, 20, had the covers firmly pulled up to her boobs.
“Our family. Close like no other,” the snap was captioned.
But of course, that wasn’t what anyone was looking at.
“Kylie hiding that baby!” commented one, while another joked that she’d been “strategically placed under the blanket.”
“If Kylie isnt pregnant then why is she covering her stomach. Oh wait let me make this more clear… why is she the ONLY one covering her stomach???” raged another, clearly sick of the mystery.
It’s the first time that Kylie’s graced Instagram since she uploaded a her cover of Love Magazine on Christmas day.
However, it was recently revealed that the star will make a blistering return to Twitter, Instagram and Snapchat as soon as she becomes a mother.
According to insiders, the 20-year-old will introduce her newborn baby as part of a well-timed comeback that will conveniently coincide with a re-brand.
The reality TV star will announce the tot’s birth online.
“Kylie has been chilling at home for the most part and just living her best life,” a source told Entertainment Tonight .
“She has really enjoyed this time away from the spotlight. It’s the first time she can remember in her entire life not being followed by cameras and she’s just trying to enjoy this privacy.”
“As soon as the baby is born, she will make an announcement and introduce the baby to her fans,” the insider added.
“She’s excited to continue to be her authentic self, and that will soon mean being a mother and sharing that with her fans.”
Naturally, the news will be a welcome development for her myriad of followers, who’ve all mourned the temporary loss of their Kardashian fave.
But it’s likely to delight Kylie herself, too. Since going AWOL, she’s been the subject of various rumours.
Some fans believe the 20-year old has been hiding the fact she was a secret surrogate for Kim and Kanye’s new baby girl.
But other fans have a different theory and it’s taking social media by storm. They believe that Kylie is in hiding because she’s not been able to have lip fillers.
In 2015, the reality star admitted to plumping her lips with filler at just 17 years old. She’s since become famed for her larger than life pout on social media.
But having filler injected during pregnancy is not advised by doctors or surgeons as they are unaware of the dangerous risks it could pose.
To date, Kylie has refused to comment or clarify.
