The X-Factor winner, who is working on her third studio album, told X Magazine: 'I think I probably will experiment with a tougher sound on some of the songs.
'But I don't like going into the studio saying, 'I'm going to do this or that' specifically. I prefer just to get in there and go with it from there.
'I'm working on the new album for next year so the new single will come early 2011.'
The singer added that touring has helped boost her confidence.
'I’ve just come off tour, and having had that experience it’s opened me up a lot more musically, especially in a live sense,' she added. 'It's helped me so much - given me more confidence and experience.'
