Glee premiered exactly seven years ago today! On May 19, 2009, the pilot episode of the FOX show aired on TV, and our lives were never the same. Over the next six years, Gleeks fell in love with the cast of characters at McKinley High School. Of course, the cast has grown up a lot since then. After all, it's been years!
