Heidi Klum says the German-to-English dictionary "changed her life".

The 42-year-old model believes the handy book - which she would have used to translate words from her native language to English - had a big effect on her life.
When asked what book changed her life, she stated simply to The Guardian magazine: "The German-to-English dictionary."
Meanwhile, Heidi - who has built a very successful fashion empire on the back of her career - previously revealed her daughter wants to take over the family business.
When asked if she would be alright with her children following in her footsteps, she said: "I wouldn't necessarily love it myself, I'm not pushing my kids in any direction. They should right now first of all be children, and learn everything that they have to learn in school.
"But for the first time, my daughter maybe like two months ago, she said, 'Mumma what do I have to do to take over your empire?' I was like, that's the cutest thing. I was like, 'Well, you go to school first and let's get good grades first', but I thought that was funny and she was like, 'Maybe I should do modelling or designing things.'"
