Time flies, doesn't it? And while the passage of time means more music from our favorite artists, it also indicates that the celebs grow and evolve.

To celebrate change (and because these transformations are astounding!) we dug up photos of what some of our favorite artists looked like when they released their first albums. Whether it's been a few years or nearly a decade, looking back at yesteryear is making us feel seriously nostalgic!

Check out the gallery above to see what Rihanna, Britney Spears, Justin Bieber and more singers looked like when they dropped their first album!
