Think the term nut job is unfair tbh. She may have a learning disability of some description or another mental problem that no one knows about. Or it may just be the fact she is 40 odd years old, never had a boyfriend and lives alone with her cat's, therefore has no real idea of the outside world and has had the world's media on her constantly for 7 weeks.
Either way, do you think she gives a shit lol. She is set to rake in £8M this year alone.
Good luck to her.
