The 17-year-old showed off a much curvier look earlier this year – prompting reports off breast and bum implants.
But Kylie has insisted she hasn't been under the knife. Instead the teen claims she's been using an enhancement cream.
Sharing a snap of her cleavage and booty on Instagram, Kylie wrote: "I love sharing my beauty secrets with you guys and this is a favourite!
"@PureLeef offers products with all natural ingredients (which is important to me) to help maintain & accentuate your curves!
"@PureLeef's butt enhancement cream & breast plumping lotion stimulate fat cells in the target areas. I started seeing results after only a month of constant use. Love their products."
But Kylie's Instagram followers weren't all convinced, with some of them suggesting that she may be trying to hide something.
One wrote: "How stupid does she think we are? As soon as she knows that the world knows about her fake butt and breasts her PR team make her do this. Tons of people will go out and buy the product too! [sic]."
Another added: "If this cream really does work, then nobody would be getting breast and butt implants!"
Earlier this year Kylie was forced to admit to plumping her lips, after her fuller pout once again sparked surgery allegations.
