In August 2011, Lengies was cast in the recurring role of Sugar Motta for the third season of Glee. Sugar, who is well-off, self-confident, and has a tin ear, first appeared in the season premiere on September 20, 2011. Since then, Sugar's singing has greatly improved, and she now performs with the main glee club, New Directions; she had her first solo line in the season's tenth episode, "Yes/No". In 2013, Lengies visited her old high school, Hudson High School (now Westwood Senior High School) to see how much it had changed, and to speak to the Student Life and Drama students about her journey of how she got to be on the hit TV show Glee.
