Tulisa Contostavlos has promised to reveal all the “juicy” details of her past relationships in her new autobiography.

The 26-year-old former X Factor judge – who has dated Unbroken star Jack O’Connell and N-Dubz bandmate Fazer – told the Daily Mirror she is not using a ghostwriter for the book, which she compared to Sex And The City.

Tulisa – who made her comeback performance at London’s GAY nightclub on Saturday night – is to tell all about her difficult year in which she faced charges of drug dealing before the trial collapsed.

She told the newspaper: “Think Carrie Bradshaw on a drugs charge.”

She added: “It’s a tell-all book. I write about everything. It’s written in a novel style, every moment written as it happened.

“I started last Christmas and I’m still writing it now. I even write about guys I was seeing at the time. But I’ve changed names.

“There will be sceptics out there who’ll say, ‘She can’t write a book, she hasn’t even done her GCSEs’ but I’ve got a genuine story to tell.

“I admit to things I’d never normally admit to. You read about me with a bottle of vodka on a Christmas Day in a darkened room, having crazy nights out with friends and the moment that I am found innocent.

“I’ve kept it juicy. I’ve cut out all the shit.”

The Living Without You singer said writing had become a form of therapy for her.

Tulisa revealed: “I didn’t go to a therapist. I don’t really believe in it. I’ve always had anxiety – since I was young. So during the trial my anxiety was through the roof. But over time I learned to manage it.”
