Helen Mirren to star in Glee
Dame Helen Mirren has singed up to lend her voice to an upcoming episode.
Celebrities such as Gwyneth Paltrow and Britney Spears have appeared on the popular show in the flesh but Helen Mirren is said to be starring as a character's 'inner voice'.
The role was written specifically for the Oscar-winning actress and it's due to be shown when Glee returns to the air in January.
A source told TVLine: "Helen came in and secretly recorded several long and hilarious monologues two weeks ago. Then she visited the kids on set, and they had no idea she was coming; they were stunned.
Helen's a big fan of the show and the message it sends out about arts education."
The star-studded New Year epsidode, which is said to have a Latin theme, will also star Gloria Estefan and Ricky Martin.
