Today's a special day for one of our fave Hannah Montana stars: it's Mitchel Musso's 24th birthday! We simply can't believe it! In honor of his big day and Throwback Thursday, we are throwing it back to each member of the cast's early days on the red carpet and comparing their looks to their current styles.
It's no surprise that Mitchel's co-stars – especially Miley Cyrus – have changed so much over the years, but all of the other cast members have grown up so much since the show began.
