A lot of people grew up watching shows like Hannah MontanaJessie, That’s So Raven, Austin & Ally and Lizzie McGuire on the Disney Channel. And the actors and actresses from the series have grown up too! Yep, this should come as no surprise considering it’s been literal years since these shows were on the air, but still, seeing how much they’ve all transformed over the years will probably make fans feel very, very old.

Take Jake T. Austin, for example. The actor, who starred as Alex Russo’s younger brother, Max Russo, in Wizards of Waverly Place, may have been a kid when the show first started, but he’s an adult now! What about Bradley Steven Perry, he played Gabe Duncan in Good Luck Charlie when he was only 11, and boy, has he changed a lot since then!

We decided to round up some then-and-now pics of the other little brothers from our favorite Disney Channel shows, so prepare to be shook over how much they’ve all grown. Seriously, you guys are not going to believe their major glo’ ups.
