Tulisa Contostavlos feared her sex tape would make her look easy.
The 'Young' singer's ex-boyfriend Justin Edwards - also known as rapper MC Ultra - leaked the X-rated footage on to the internet in March this year and 'X Factor' judge Tulisa feared the fall out from the scandal would irrevocably damage her reputation.
In an extract from her upcoming autobiography 'Honest, My Story So Far' - which has been serialised by The Sun newspaper - she reveals: ''It felt as though there was a massive axe swinging above my head.
''My job as a judge on 'The X Factor' was to smile and be smart and funny. But underneath I was petrified of being made to look like some kind of slapper in front of the nation.
''I would try to put the whole thing out of my mind but it would creep back - it was pretty much all-consuming.''
Tulisa, 24, also revealed the support she received from her boyfriend at the time, actor Jack O'Connell, helped her come to terms with what had happened.
She recalls: ''There was a text from Jack asking if I was OK. He had just arrived back in London and we met up the next day.
''It turned out he'd been on a plane when I'd texted him. As soon as I saw him everything started to feel better, easier.
''For the next three weeks he never left my side. It was the distraction I needed. And as time went on I started to feel stronger.''
Tulisa took Justin to court to make him confess he was responsible for leaking the footage and sued him for £100,000 for breach of privacy.
