I remember the first time I saw and heard Nadine sing.. When she auditioned at the Irish Popstars (which surprisingly enough was actually aired here in Norway), and I loved her voice straight away. I was so bummed when she got kicked out of the show. It took me a while to later realise she was in a new band (Girls Aloud of course).
I still think so has one of the best and most pleasant to listen to female voices in the world.
New performance:
