Sarah Harding is so nervous about the new St Trinians movie, she feels she is sitting an exam.
Not only has she appeared in the movie, she is singing the theme tune too.
Talking to us at a Stroke Association charity bash at Swarkovski, she said: "The first time I will see it will be with the girls, Tommy, my mum and my auntie. It's so nerve-racking. Then she was off, telling us "I'd love to have a big night out but I've got to work in the morning." What a light weight.
