Kirstie Alley is writing a new book in which she promises to reveal the secrets of her lovers and men she has known.
The former 'Cheers' star is currently penning 'The Art of Men' and she has vowed to dish the dirt on the behaviour of guys she has dated and famous men she has known and worked with, such as Ted Danson, Woody Allen and her friend Jonathan Knight - a member of New Kids on the Block.
Kirstie - who was previously married to Bob Alley and actor Parker Stevenson - is quoted by In Touch Weekly magazine as saying: ''I've lived a pretty wild life. And I wanted to share the good, the bad and the ugly so that my readers can find humour in their own lives and have certainty that they can survive anything.''
The 61-year-old actress has also promised her fans the tell-all tome will be even ''sexier than 'Fifty Shades of Grey''' - the blockbuster erotic book about the bondage and sadistic sex life of a couple.
Kirstie - who has been rumoured to be dating dancer Serge Onik in recent months - has always been open about her love life and previously boasted she used to have sex for two hours every day.
The former 'Dancing with the Stars' runner-up admitted she had an insatiable sexual appetite but her marathon romps still couldn't bring her happiness in her relationships.
She has said: ''The way I used to pick guys was so shallow. Hot? OK, that'll be my husband. But here's my big revelation. I decided that in the best of times you have two hours of sex a day, so you have 22 hours left.''
