At this point, Britney really has nothing left to prove. She's not a "flop", she's a multi-million selling female artist who has maintained worldwide success for 13 years. She will never fade out because of the huge impact she had and still has over the whole world, the industry and her huge following. The UK's interest for Britney has slowly been deteriorating since Circus for many reasons already stated; performing and auto-tune being at the forefront of this. However, sales for the UK do not determine the overall success of her as an artist nor the album. To those who just comment Britney hate, you really are clueless so do try to save yourself the embarrassment of looking stupid.
