Susan Boyle is cementing her star status even further by releasing her own memoirs.

The Britain's Got Talent singer has signed a deal to document her rapid rise to fame in 2009.

"I'm writing this book to try to show that you shouldn't judge a book by its cover and I hope it will benefit other people," the 49-year-old said.

"My story demonstrates that you shouldn't just look at the label, you should look at the whole person, emotionally, physically, mentally and spiritually, and I hope that telling it will show that dreams are not impossible, if you've got courage and a willingness to go on - no matter what the circumstances."

The book, The Woman I Was Born To Be, will be published in the autumn.
