Sad thing is she left Atomic Kitten just as they were becoming big and could have had a successful pop career. However, she left just as the whole reality show culture was kicking off and found her niche that way.
Kerry never even did any singing during the blink-and-you'll-miss-it time she was originally in Atomic Kitten. I believe she's actually come out and said this herself.
One thing she did have going for her when she was younger was being naturally gorgeous. Now she's just a walking advert for why drugs are bad. Someone on here described her as looking like a sixty year old barmaid and they are so right. It's genuinely sad.
