BEHOLD THE PASSAGE OF TIME!!! The good people at decided we needed to be reminded that we're all mortal and this is not a dress rehearsal, so they've cobbled together some gifs (by way of the less said about the accompanying cartoon image the better) of Disney stars ageing. 

Needless to say, the most remarkable the ones featuring Miley Cyrus, Britney Spears and Justin Timberlake (obvs)...

As for Selena Gomez, well, she's not changed a bit. In fact, she's not even changed an iota since she was on Barney with Demi Lovato - which I get to watch it EVERY DAY. So lucky. 

Again, the less said about the accompanying cartoon image, the better. 

If you'd care to see the likes of Hilary Duff and Shia LaBeouf ageing, make your way hither
