Lea Michele turns 27 today, and as she's been growing up offscreen, she's also shown a major transformation on Glee. Rachel Berry has come a long way in just four seasons, evolving from a fame-obsessed showoff into a more mature, well-rounded woman who's earned her place in the spotlight. When we first meet Rachel in all her argyle-and-knee-socks glory, she's getting "slushied" in the hallways of McKinley High School. Now, coming into the show's fifth season, Rachel is a bona fide New Yorker who's ditched the self-centered dramatics and put herself out there in the world of show business. In honor of Lea Michele's birthday and the upcoming season of Glee, let's take a look at Rachel Berry's onscreen evolution from New Directions to NYADA.
