Stylish Stardolls Keira Knightley and Sienna Miller are starring in a new film The Edge of Love .. .and Keira is trotting out to the edge of her own comfort zone playing a singer. The 23 yo star described the experience in an interview with Total Film: “I did some lessons with a voice coach because I can’t sing. There were 100 extras and John (Maybury, the director) was like, ‘Now you’re going to sing…’ “I’ve never been so frightened in my entire life.” “I don’t know how singers do it. I never want to have to do it again. I don’t want to be a rock star.”

So although all reports are that she has a very nice voice I guess we won't be getting a Scarlett Johannsen cover album from Keira anytime soon.

The Edge of Love is out in the UK on June 27, and is about two women vying for the attention of poet Dylan Thomas. It also stars Sienna Miller. That's her standing in the back.
