Harry Potter author JK Rowling has been named in an American list of the world's billionaires.
The list, published by the posh magazine Forbes, shows she has made $1bn. In Britain that works out as a whopping £530m.
Last year JK, who is now writing a sixth Harry Potter book, was named as the richest author in the world.
Microsoft boss Bill Gates was named as the world's richest man for the 10th year running with a $46bn fortune.
That is £24.7bn in English money.
