X Factor's Tulisa to release 'tell all' book

X Factor judge Tulisa Contostavlos has promised fans there is "lots to tell" after it was revealed she is releasing her autobiography later this year.

The 23-year-old will also publish two novels in 2013 and 2014 as part of a book deal she signed with publisher Headline.

She said: "I'm really excited to start work on these books. Having my novels published is a dream come true for me. I'm also looking forward to sharing my life story so far, I've got lots to tell."

The N-Dubz star is expected to tell all about her childhood in north London, where she was a carer for her mother who struggled with mental illness, and her rise to fame.

Deputy publishing director Sarah Emsley said: "Tulisa is an incredibly talented writer and musician and, as her mentoring of Little Mix on this year's X Factor has shown, she is an inspiration for young women everywhere."

She added: "Tulisa's story has incredible breadth and depth for someone so young, and we are absolutely thrilled that she has chosen Headline to be her publisher."

Managing director Jane Morpeth said early material from the novels showed the star had "a wonderful grasp of plot and characterisation".
