Up-and-koming Kardashian sister Kendell Jenner just turned 18 two weeks ago, so, naturally, she's already posting barely legal photos of herself online.

The "aspiring fashion model" gave her nearly 6.5 million (?!) followers a "sneak peak" (sic) of her recent photoshoot with Victoria's Secret's house photog Russell James which just happened to feature Jenner in a nip-slipping mesh top.

"Can't wait for you guys to see the rest of the photos!" Jenner exclaims. No doubt those will be behind a paywall.

James also shared the same photo on his own Instagram account, albiet in color because art.

TMZ spoke with sources close to Jenner's father Bruce, who is apparently absolutely fine with his daughter giving away the goods just 16 days after being legally allowed to do so, "and insisting he's proud of her no matter what she does."

I have a feeling he's going to be held to that statement sooner rather than later.
