Geri Halliwell says she loves toilet humour and doing accents. The former Spice Girls star, who is now a children's author, admits her mischievous side leads her to play pranks on her friends.
She said: "A lot of people have said that I've got a voice that speaks to children. I think I've got a cultural naivety to me. I'm childish. I have a huge toilet humor - I love talking about poo and wee."
