It's hard to believe that the former Disney starlet, who we've literally watched grow up before our very eyes, is celebrating her 22nd birthday today. From Wizards of Waverly Place to Princess Protection Program and Ramona and Beezus, Selena has starred in tons of our favorite Disney Channel shows and movies. Plus, let's not forget about her guest appearances in The Suite Life of Zack and Cody and Hannah Montana. Those were the days. Sigh.
