Heather Elizabeth Morris (born February 1, 1987) is an American actress, dancer, and singer, most known for her role as old-cheerleader Brittany Pierce from the musical/comedy series "Glee". Morris' first appearance on television was in 2006 on "So You Think You Can Dance?", followed by "The Beyonce Experience", "Satruday Night Live", "The Ellen DeGeneres Show", and several more. Sometime afterwards, while Morris was taking acting lessons and pursuing an acting career, she was asked by Woodlee (co-producer of Glee) to teach Beyonce's "Single Ladies" dance to the actors. During the same time period, the show was looking for someone to fill the role of a third cheerleader, which Morris ended up filling as "Brittany Pierce".
