Soprano-turned-pop star Charlotte Church has signed a deal to write her second autobiography - at the tender age of 20. The Welsh singer released her first tell-all, Voice Of An Angel: My Life So Far when she was 14, and believes her recent family dramas and two rocky teenage romances will provide sufficient material for an undated version. Church has vowed to tell her fans exactly what she thinks about her rivals, such as Girls Aloud singer Cheryl Tweedy and aspiring chart star Paris Hilton. She says, "I'm not holding back and I'm not asking anyone's permission to name them. Why would I? It's my experience, my life and my book, I don't care what people think. "There's been a lot written about me and now I want to put it all in my own words." The untitled book will hit shelves in September 2007.
