Zoe chats to our entertainment show Newsround Lite about her debut single and her hopes for the future.
Your new single Treat Me Like a Lady, what's it about?
It's a funky disco pop track. The message is that sometimes you can get taken advantage of and things like that. And if you want to hang with me I like to be treated like a lady - wined and dined, and that sort of stuff.
Is it a new song or a cover?
It's a new song. Sarah Whatmore wrote the track.
Why did Sarah write it for you, why didn't she keep it for herself?
Well, she recorded the song first and then I got the track played to me and I really liked it. Simon Fuller gave the go-ahead to see what I sounded like on the track. So I recorded my vocals and then he came back and really liked it.
I really liked being in the studio trying to work out which single was going to be the first release, and then we picked that one.
Sarah's really pleased that it's going to be the single, cos if it really does well it's going to be a proud moment for both of us - her as a writer and me as a performer.
Do you feel you've been kept in the shadows while Gareth and Will have had all the publicity?
Not really, because they (record label) didn't want to rush me, they wanted to keep with the plan and that was to release a single in 2003.
I think they wanted to take me away from the Pop Idol status and be Zoe Birkett the new artist and not have the Pop Idol tag.
Are you pleased that you haven't had to go up against, Will, Gareth or Darius in the charts?
I'm pleased because it's given me time to have a good 11 months in the studio and sit down and write with people and put my stamp on the music and haven't had to quickly get a song and put it out.
And build on who I am - because I've just turned 17. I'm still learning about myself. I'm pleased that I have waited.
How has the last year changed you?
I feel I have had to do a lot of growing up. I now have a little apartment in London with my mum and it's all a bit adult-like but I'm still a child really!
Do you feel you've lost your part of your adolescence?
Not at all, I've been dancing and singing since I was three, it's been my life, it's always been what I wanted to do and this have been the lucky stepping stone for me, it's been an amazing year.
