Julia Roberts refuses to join the ranks of stars making cameo appearances on musical TV series GLEE - despite branding herself a "great singer".
The hit U.S. comedy, about a high school show choir, boasts a huge list of celebrity fans, and A-list stars including Jennifer Lopez and Britney Spears have been confirmed for roles in future episodes.
Glee creator Ryan Murphy recently directed Roberts in her new movie Eat Pray Love - but she is adamant he'll never persuade her to sing on the show.
She tells Reuters, "(Actor) Billy Crudup and I were in a Woody Allen musical a couple of years ago and so he said, 'Oh, you're a great singer,' and my husband said, 'You are a great singer.' So, now I'm going to say I am a great singer, (but) I'm not just going on Glee."
