Chris Colfer wants Dame Julie Andrews to have a cameo in 'Glee'.

The 21-year-old actor thinks the 75-year-old screen and stage legend - famous for her roles in musicals 'Mary Poppins' and 'The Sound Of Music' - would be perfect to play his character Kurt Hummel's grandmother on the TV show.

He said: "I just want Julie Andrews in it, that's all. I just want Julie Andrews to come and play my grandmother and then I'd be happy. That's all I need."

Chris' co-star Lea Michele loves it when 'Glee' gets a guest star but prefers it when show boss Ryan Murphy keeps their appearances a secret from the regular cast.

In a joint interview with Chris for Britain's Marie Claire magazine, she said: "I like being surprised - I say this all the time. I like hearing through the grapevine that Gwyneth Paltrow's going to be in next week's episode. I think that not knowing is definitely more fun."

Previous guest stars have included Gwyneth Paltrow - who has had two separate mini-runs in the show as substitute Spanish teacher Holly Holliday - and Britney Spears who had an episode dedicated to her music.
