6. Selena Gomez as Alex Russo in Wizards of Waverly Place
My, but they grow up fast, don’t they? Selena was 15 when she was cast as Alex Russo, a teen who, along with her siblings, inherited their father’s magical abilities. Though the popular Disney Channel series ended its run back in January of 2012, fans rejoice: The wizards are coming back for a one-shot television movie on March 15, 2013 called The Wizards Return: Alex vs. Alex.
