Millie Bobby Brown just turned 13 on Sunday (even though her soul—and her fashion sense—is much, much older, obviously). To celebrate, she took to Instagram and posted a throwback video that will make your day.

The video is of Millie when she was just seven years old, singing her heart out. It's equal parts adorable and downright impressive.

"6 years ago.. I made videos on my computer I honestly don't know why but I loved it.. I want to share this video with you! Thank you all for my Birthday wishes 🎉💜 love and light 💛," she captioned the video.

Millie wasn't the only one celebrating her anniversary of being alive. Zac Efron, one of her many, many celebrity superfans, posted an Instagram shoutout to mark the occasion. And yep, that is a Stranger Things shirt he's wearing.

Happy birthday, Millie! Please put out an album soon. Or at least a single. Or even just more Instagram clips. Honestly, we'll take whatever we can get.
