In reply to really.

Nah, Nadine isn't as fame hungry and hasn't been given the same opportunities as Cheryl but if you watch her in interviews Nadine has plenty personality.
As for music, Cheryl's a million lights was an album of rejected rihanna and rihanna-esq songs where as Nadine's album although not great had better stand out songs.
T be honest, after hearing cheryls talking voice i realise why her singing voice is so bad. Her voice is so monotone
