18 Celebs Who Became Famous As Little Kids, And We Blinked And They Grew Up

Every day on the internet makes me feel just a teeny bit older — and the most recent thing that made me contemplate my retirement plan was seeing how much Jacob Tremblay grew literally just in the time it took from The Little Mermaid production to its theatrical release.

Jacob was only 12 when he first landed the role of Flounder — and now he's 16! And just like Jacob, there are so many talented young actors and singers who've been on the scene for so long that now they're teens and twentysomethings. Let's take a look back:
