Keira Knightley admits she was terrified at having to sing for her role in new movie Can A Song Save Your Life? The Brit beauty took singing lessons in preparation for the movie, but still suffered terrible stage fright ahead of shooting for her role. “I was terrified but in the end it wasn't actually as bad as I thought it was going to be,” says Keira. “Everyone on set made it a really wonderful experience and it seemed to work. But I'm not a singer and I'm still not a singer. Let's just say I won't be putting an album out!”
