Celeb chef Jamie Oliver has finished reading his first complete book at the age of 38.
Jamie suffers from dyslexia, which makes reading and writing harder to do.
About one in ten children in the UK have the condition.
Even though the famous chef written almost 20 cookbooks, his dyslexia has made finishing a whole book difficult for him.
The father-of-four said: "Until recently I'd never got through a book. But I read Catching Fire. I loved disappearing into a story."
What is dyslexia?
Dyslexia affects the way you recognise the sounds that groups of letters make.
It can make it hard to read and write amongst other things.
It doesn't affect intelligence and it's not a disease or illness - it's a condition you're born with.
Some people learn special techniques to help them cope with dyslexia whilst others need special support.
