Kylie Jenner stunned fans on Monday with a couple of 'naked' bikini shots that appeared to catch numerous fans out at first glance.
The reality star shared two images to her 345 million Instagram followers posing outdoors in figure-hugging nipple-print attire.
The close-up shots of the 24-year old - taken from below - emphasised her chest, while she sported black sunglasses and silver earrings.
Within four hours the post - captioned 'free the nipple' - had attracted a whopping 5.5 million 'likes' and over 30,000 replies.
One user joked: "You gotta put up a warning. I thought I pressed the wrong app."
Another added: "I got a really scared a for a sec," while a third replied: "Just fell to my knees in Walmart!"
A fourth wrote: "The jump scare was real."
Not every follower found the funny side, however, with one commenting: "Do you realise how many young women look up to you and your sisters? Put some clothes on, you have more to offer than sex. The Kardashian influence has done so much damage to our young girls. Don't you want to do better?"
Kylie gave birth to her second child with her rapper boyfriend Travis Scott, 31, just three months ago. The pair are yet to reveal the boy's new name after scrapping his original - Wolf.
Fans of the star were split last week, meanwhile, as she donned another daring fashion ensemble on the social media platform.
Followers dubbed her new striking outfit something a "a low budget Spider-Man" would wear, while others claimed it was another "perfect" look for the mum-of-two.
The Kylie Cosmetics founder shared a series of snaps and clips from a recent photoshoot, which saw her show off a netted body suit - complete with a fish-net face covering.
The edgy new shoot saw the star pull off a long-sleeved pink leotard and gloves, worn over pink stockings giving a catsuit feel to the outfit.
Kylie added pleather over-the-knee boots to complete the look.
For every "You are my super hero," complement, however, there was a much less appreciative "low budget Spiderman" remark.
