Dannii Minogue has started writing her autobiography despite claiming she'd never release one.

The Australian beauty - who is expecting her first child with boyfriend Kris Smith - has reportedly begun penning her life story and five publishers are keen to release it.

The book will cover her rise to stardom on Australian soap 'Home And Away', pop career and failed marriage to fellow actor, Julian McMahon. Fans are also hoping to read about her obsession with Botox as well as her feud with Sharon Osbourne - who used to sit alongside her on the judging panel on UK talent show 'The X Factor' - and the truth about her frosty-friendship with Sharon's replacement Cheryl Cole.

A source revealed: "A deal is expected to be confirmed very soon."

However, in 2008, Dannii vowed never to write an autobiography like Sharon and her the other judges Simon Cowell and Louis Walsh.

She said: "I can't ever imagine wanting to release a book. I mean to what end? So people can know every detail of my life? No thanks."

"I come from a very private family and I can't imagine it going down too well."
