High Quality Content by WIKIPEDIA articles! Blaine Anderson is a fictional character from the American musical comedy-drama television series Glee. Played by Darren Criss, Blaine was introduced in the sixth episode of the second season as the openly gay lead singer of the Dalton Academy Warblers, a rival show choir to New Directions, the show`s primary musical group. Blaine initially served as a mentor for New Directions member Kurt Hummel (Chris Colfer). Chemistry between the two, combined with fan support for the couple, led series creator Ryan Murphy to pair them romantically. Their relationship has been well-received by critics, and they have been named "one of the most beloved TV couples of the millennium" by Jarett Wieselman of the New York Post. At the beginning of the third season, Blaine transfers to McKinley High and joins New Directions; concurrently, Criss was promoted from recurring guest star to the show`s main cast.
