Menzel had a recurring guest star role in the television series "Glee" playing Shelby Corcoran, the coach of the rival glee club Vocal Adrenaline. When the series first premiered, "Glee" fans (known collectively as 'Gleeks') had noted a strong physical resemblance between Menzel and Lea Michele, who portrays the character of Rachel Berry. According to her then-husband, actor Taye Diggs, Menzel had expressed interest in possibly guest-starring as the biological mother of Rachel. The character was introduced in the episode "Hell-O". Lea Michele and Idina Menzel sing together "I Dreamed a Dream" from "Les Misérables" and "Poker Face" originally by Lady Gaga. Menzel returned to "Glee" in season 3 episode "I Am Unicorn", her role this time as a teacher causing trouble for Rachel, Quinn, Puck, and former flame Will Schuster.
