She's promoting a stress book at the moment that is probably ghostwritten. She then goes on about how she's written children's books, cookery books, designed fashion ranges, presented TV and radio all while being a mum.
She's hardly dedicated herself to one craft and probably has minimal input to each of the projects she has put her name to. The only thing I can actually comment on is the presenting and she's pretty dire at that.
Just seems like a sad world where you can get all these opportunities thanks to nepotism and fame. They no doubt take away chances from actual writers or designers.
