'Pregnant' Kylie Jenner might be missing her regular revealing body shots posted to Instagram, since she has shared some unseen 'naked' pictures on her app, which costs subscribers $2.99 (£2.22) a month.

The 20-year-old reality television star – who is reportedly pregnant with her first child with rapper boyfriend Travis Scott – posted a sneak peek of the throwback photos to her 99.7m followers.

The two pictures were taken in front of a trimmed hedge, with the social media phenomenon posing in the nude, protecting her modesty with a white robe.

Her short raven hair is styled away from her face, while her makeup is flawless, using neutral tones and her trademark matte lipstick.

Jenner captioned the post, which has caused a social media frenzy with 2.2m likes and counting, with: "posted some exclusive polaroids on The Kylie Jenner Official App from the past few years."

One confused fan commented: "Is this the maternity shoot?"

While another put: "Are you pregnant?" Jenner has neither confirmed nor denied the rumours that she is expecting.

Jenner writes about the shoot on her app, which was photographed by Brendan Forbes. She also worked with Forbes on her Barbie-inspired shoot for Flaunt magazine.

The Kardashian-Jenner clan have been shrouded with pregnancy reports in recent months, since 37-year-old Kim is expecting a child by surrogate with husband Kanye West in January, while Khloe, 33, is also reported to be pregnant with her first child with boyfriend Tristan Thompson.

Fans are further convinced that both Kylie and Khloe are pregnant, since momager Kris Jenner said in a recent episode of Keeping Up With The Kardashians: "I used to pray that one of you guys would have a baby and now it's like a faucet that we turned on that won't turn off," she confessed.

"The fact that I have all these grandchildren..."

Jenner, who usually posts regular outfit pictures onto social media, has only been posting close-ups of her face in recent months, only sharing throwback snaps of her whole frame.

She was previously in a relationship with rapper Tyga for three years before getting into a relationship with Rihanna's ex-boyfriend Scott, 25, in the spring of 2017.
