When the Queen photobombed hockey athletes at the Olympic Games, it gave Sharyn Jones a great idea for a children's book.
She's written Woof, The Photobombing Sock Puppet, a children's book, which was published last month.
"If the Queen can photobomb, then I can write a story about it," the author says.
"It was so fun to see the Queen having fun and photobombing, children love to photobomb as well."
The story is about shy Bobby Brown who wouldn't have his photo taken.
