Tracy Beaker author Jacqueline Wilson has been honoured by the Queen after she was made a Dame.
That's the women's equivalent of being made a knight, and she was given the title for services to writing.
She's sold more than 20 million books in the UK and her stories have been translated into 34 languages.
Lots of other people were honoured at the ceremony, including ex-England rugby coach Brian Ashton, who took his team to the World Cup final last year.
Jacqueline Wilson's been honoured for her work before. From 2005 to 2007 she was the Children's Laureate, which is a position given to important kids' authors.
Lots of her books, including The Story of Tracy Beaker and The Illustrated Mum, have been made into TV shows.
