The actress has been inspired to starting penning tracks by her role in new movie `My Own Love Song`, in which she sings a song written by Bob Dylan, and admits she is now trying to decide what to do with the material.
She told Rolling Stone magazine: "I don`t know what you call it. It just comes out sometimes, and I don`t know if I`m ever going to be able to share them with anybody, except my neighbours, who unfortunately don`t have a choice!"
Renee admits she was very nervous about lending her voice to the Dylan track `Life Is Hard` which features in the Olivier Dahan-directed film, because she was worried she wouldn`t be able to do it justice.
She said: "It was terrifying, absolutely terrifying."
The version Renee performs is featured at the movie`s climax, while Dylan`s own interpretation plays over the end credits.
In the film, the 41-year-old actress plays a former country star who sings the song at a garden party just before she is reunited with the 10-year-old son she abandoned after a car accident when he was three.
