Skai Jackson has literally grown up right before our eyes. It's amazing! She recently posted a photo on Twitter where she looks like a full-fledged adult, and it's so shocking to watch her glo up like nobody's business. Since we watched her as a little kid on Jessie, her transformation is especially pronounced. Skai is a teenager now!

For instance, Ariana Grande has completely switched up her look. While she used to rock curly hair, now she's all about her signature high ponytail. The titular baby from Good Luck Charlie, Mia Talerico, is in elementary school now — she's a baby no more! And while Noah Cyrus has been walking the red carpet for ages, she's fully come into her own style now.
