I very rarely see these posted anywhere and I have them "hoarded" so I figure I may as well share. It's a post she shared then deleted to Instagram, and well, quite a bad lip slip I'd say. Original, and AI Upscaled for posterity.
This isn't a fake, not to my knowledge. I'm 99.9% sure this came straight from the source, then she woke up a bit and realised and deleted it lol. Enjoy.
