Brittany Susan Pierce is a fictional character from the Fox musical comedy-drama series Glee. The character is portrayed by actress Heather Morris, and first appeared in the show's second episode, "Showmance". Brittany was developed by Glee creators Ryan Murphy, Brad Falchuk, and Ian Brennan. In Glee, Brittany is a ditzy cheerleader, or "Cheerio", for the fictional William McKinley High School, and a member of the school's glee club led by Will Schuester. Morris was originally hired to teach Beyoncé's "Single Ladies" dance to the Glee cast. At that time, the series was looking for a third cheerleader, and Morris landed the role. Morris was upgraded to a series regular in the series' second season, in which Brittany is given a larger storyline, solos and dance routines to perform.
