Kelly Osbourne is writing an autobiography.

The 23-year-old star - who shot to fame on fly-on-the-wall MTV show 'The Osbournes' with her rock star dad Ozzy, mother Sharon and brother Jack - has signed a deal with Virgin Books and will release the tome next year.

Kelly's mother Sharon's autobiography 'Extreme' sold more than two million copies when it was released three years ago, and publishing bosses are hoping Kelly's book will do even better.

Virgin Books boss John Sadler said: "We can't wait for Kelly to take the book trade by storm in the way her mother did."

The autobiography promises to be a tell-all account of Kelly's life, including insights into her drug addiction and spells in rehab.

It will also give the lowdown on her bitter feuds with other celebrities, including singer Christina Aguilera.

Outspoken Kelly recently warned singer Dannii Minogue to stop badmouthing her mother Sharon.

The feisty star admitted she was sick and tired of 'X Factor' judge Dannii insulting Sharon since she quit her judging role the British TV talent show and ordered Dannii to keep quiet or incur her wrath.

Kelly said: "Dannii is spineless really. She said nothing to mum and even gave her an end-of-series gift. If she does not stop bad-mouthing her she will have me to contend with."
