We've known for a long time that Kylie Jenner was morphing into Kim Kardashian, but this is absolute proof.
Kylie was hanging out with her sister Kendall Jenner and brother Rob Kardashian at the home of her dad, Caitlyn Jenner.
That's the good news.
The bad news is, Kylie seems to prefer the company of her reflection.
Rob catches his half-sister admiring herself, and probably Snapchatting a selfie, in the bathroom mirror.
He tries to get her attention by calling out to her.
"Hey. Hey! YO!" he says in a video on his own Snapchat.
But Kylie is so mesmerized by her own reflection that all outside noise has gone nil.
That, or she just can't be bothered.
Mind you, Rob is standing in the doorway about three feet away from her, so if she can't hear him, she's deaf.
After Rob's efforts have failed, Caitlyn shouts, "KYLIE!" and she finally turns around, looking like a deer in the headlights.
Sorry, I'm just trying to get the perfect angle here. I'm not used to Dad's lighting scheme.
There's no shortage of self-love in the house that narcissism built.
