You may think that some of your favorite Disney Channel stars were always Disney kids, but some of them have actually appeared on Nickelodeon shows!

Meanwhile, Good Luck Charlie's Shane Harper was on Zoey 101. Did you know that? His spot in the series was very quick. If you blinked too fast, you have missed it!
