She talks about her time on the X-Factor
"I mean, they do advise you not to be too professional. They say, whatever emotion you feel, just let it out. If you're acting too professional, that will be your biggest downfall.
"It's like, people on that stage are crying for their dreams. All that anger or sadness or anxiety that you might feel in the week builds up, and builds up, and then it's just that one moment on a Saturday night. On live TV. [The producers] do say: don't repress it. Otherwise you don't look human."
Her relationship with Simon Cowell
'If I don't like something you're saying, you will know about it. I'm not one to beat around the bush, I don't even let my mum and dad tell me what to do.' And Simon said: 'Alex, if I am ever wrong - which I never am - I will apologise to you. But if you're wrong, you need to learn to apologise to me.' Which is fair enough, isn't it?"
Her rejection before X-Factor
"I was told by a specific person in a management company that he wouldn't take me on because he had 'way too many' black people on his books. Like, huh? Why do you have to talk about me in terms of my skin colour?
Her fears after the attack on Leona
"I mean, I don't ring management for a security guard to go down the road but I tend not to go out very much by myself. It can take an hour or more to go round the corner for a pint of milk, so generally I get someone else to do it.
"The Leona attack is obviously going to freak out any artist. It was at a book signing, it couldn't have been prevented. It does make you nervous."
and much more.
