Book Searching!!!!!!

Hi all I was wondering if any of you can help me pleeeeeeease ??

Well some time ago there was a woman on the program "Loose Women" the girly chat show hingmy.... she murdered someone for her friend, and was interviewed on why she did it and she says she done it out of loyalty for her friend. She was quite an unusual woman, seemed a little drunk but she might not have been. Anyway, she wrote a book, and I am looking for it for a friend for Christmas but can't even remember her name Anyone have any idea please?

I know who you mean, but cant remember her name ,

Hmm its baffled me lol
