She seems like a pretty bright girl to me who knows how to play the role she has landed.
I saw the program, and although she was joking about "being fabulous" etc, she blatantly was very much a normal mum underneath, first thing she was interested in for houses was if they were safe for her kids etc.
I reckon that she is :
Fairly inteligent
Fiercely loyal to her husband
A loving mum of her kids
I think she looked better when she was a bit heavier, when the spice girls first started, but she is still fit now even though she is a bit too skinny.
I think most of the people having a problem with her dont seem to be able to differentiate between who she really is, and what she gives the press/cameras in order to continue her career as "someone famous"
