Hannah Montana fans, brace yourselves. We're about to present you with a set of facts that will boggle your brain. It's been 11 whole years since the show premiered in 2006. Can you even believe it?

It's been ages since Hannah first graced our television screens, so obviously the cast has changed a lot. You've probably followed Miley Cyrus through her various incarnations over the years — from twerking Miley to "Wrecking Ball" Miley to Happy Hippie Miley — and she's almost evolved into a new person now.

While Emily Osment is currently starring in the hit Freeform show Young & Hungry, other cast members have completely dropped out of the spotlight. Morgan York, who played "Saint" Sarah, lives in New York and is a YA fantasy author. (Plus, her hair is in a very short crop now.) Ready to take a trip down memory lane?
