These 13 Celebs Look Completely Unrecognizable As 13-Year-Olds

They're all such cute teenagers!

No matter who you are -- unless you're Kim Kardashian, maybe? -- being thirteen years old is an embarrassing, emotional experience. Between puberty and questionable fashion fads, odds are that when you uncover those old school picture day photos once you're all grown up, you're going to wince.

But things are a lot different for kids these days according to Anderson Cooper, who last night (October 5) unveiled his latest CNN report, "#Being13: Inside the Secret World of Teens," which investigated the effect of social media on today's young people. To promote the show, he and many other CNN anchors tweeted pictures of themselves at the tender age of thirteen.

It certainly got us wondering -- what did some of our current favorite celebrities look like before they'd gotten into high school? Like the cutest, dorkiest, most wonderful kids in the whole world, evidently:

    Aw man, remember when the Biebs was just a tiny adorable child?
