The youngest self-made billionaire of all time was the model of modesty when news of her achievement broke this week.
But the reality TV star turned make-up magnate made it all sound sooooo easy …
“I popped up at a few stores, I did my usual social media – I did what I usually do, and it just worked,” she sighed.
“But it’s a nice pat on the back.”
Kylie’s fans, including the 128.5 million Instagram followers and 26.7 million on Twitter , were far more effusive.
“What a role model! Now the rest of the Kardashian-Jenner clan will be keeping up with little sister Kylie.”
But not everyone was hailing the billion-dollar baby as a business icon.
Kylie found fame on the back – and backside – of her elder sister, Kim, in the hit reality show Keeping Up With The Kardashians, which began in 2007 when Kylie just nine years old.
Then she built her $900million – £683million – cosmetics business through narcissistic and over-sexualised social media posts featuring a perfect pout secretly created by lip-fillers.
A pout many impressionable youngsters tried to recreate by sucking on shot glasses, ending up bruised and hurt by the Kylie Jenner Lip Challenge.
So is it any wonder many parents fear Kylie’s record-breaking wealth will reinforce the message being sold to youngsters alongside those £22 lip kits – that success is measured in physical attractiveness and social media fame.
Good Morning Britain presenter Piers Morgan, 53, was one of the first to express concern. “Self-made billionaire?” he scoffed.
“If Kim Kardashian hadn’t made a s-x tape – which got leaked – and then built a whole billion-dollar family franchise out of it, none of them would ever have been heard of.
“We don’t want young girls thinking the way to get on is to be a Kardashian, because that’s madness.
“Especially with International Women’s Day coming up, is this what we’re celebrating?”
The Loose Women panellist Janet Street-Porter, 72, also piled in calling Kylie “a shocking role model to young girls” and asking: “What has she brought to the modern world and what will she be remembered by?
“A lot of lipstick and big lips, and a lot of containers which may or may not be biodegradable. What is the impact on the environment?
“Anyone who, at 17, puts lip fillers in, then sells lip products put on artificially filled lips… it’s not a value based on something I’m comfortable with.”
But fellow panellist Coleen Nolan, 53, disagreed: “She’s worked having a famous family to her favour – that’s a good business brand.
“Some people would take the money and sit on a yacht all day, but she has turned it into her own business.” Many female celebrities are increasingly concerned at the influence of the image-obsessed Kardashian-Jenners.
