No one's look stays the same forever, but every once in a while a celebrity tweaks their appearance so much, they look unrecognizable! From plastic surgery to no makeup to weird makeovers, you won't believe these are pictures of the same person.

MUST SEE: Heidi Montag, Courteney Cox, and More Celebrities Who Completely Changed Their Face Over Time

Unfortunately for these celebs, we live in the Internet age where no old photo, makeup-less selfie, or embarrassing style evolution is ever forgotten. Just look at Ariana Grande, who might be a tanned, pony-tail clad pop star today, but a few years ago was a pale-faced, curly-haired Disney star without an ounce of her current Dangerous Woman sass.

But perhaps the most shocking transformation is Kylie Jenner, who went from a thin-lipped, normal-faced teenager to Kim Kardashian's pillow-lipped mini-me. She has admitted to having lip fillers, but she maintains the rest of her face is just ordinary aging and improved makeup skills.

"You guys have watched me grow up since I was 9. My face is going to get different," she said in 2015. "Now I know how to do my makeup, contour and everything."
