well as usual Simon will be back next year !!!
Louis will be back too because hes been there from the very beginning and he's like part of the furniture he'll never leave
i cant see Mel B coming back her attitude has irritated me and pretty sure Simon is fed up with her too
i doubt she'll be asked back atall lol so she's a definite replacement
Cheryl will probably be asked back and she'll probably think about it this time but she'll either come back or be replaced
i think Sharon should come back
