Drew Barrymore became so inspired while portraying a songwriter in new romantic comedy Music & Lyrics, she penned a tune for her favourite singer.

The actress is hoping to present the song to indie pop singer Jenny Lewis.

The actress says, "I was listening to this album by Jenny Lewis called Rabbit Fur Coat; it was just my favourite album of 2006.

"I was obsessed with it and she made me think I could write a song. It's probably really terrible.

"I actually know her, so I should show it to her and see what she thinks."
