Stars Celebrate World Book Day with Adorable Costumes

and were among the thousands of parents whose children channelled their favourite literary icons for on Thursday.

Stars took to Instagram to proudly show off their brood's costumes as they headed to school in honour of their favourite book characters.

Sharing snaps of her daughters Rose, four, and Belle, three, Stacey revealed they'd both dressed up as Matilda and Red Riding Hood.

She wrote: 'Red Riding Hood and Matilda are ready for nursery. Rex is celebrating World Book Day tomorrow and he wants me to make a Diary Of A Wimpy Kid costume so wish me luck today.'

Lucy then shared her own sweet images of her son Roman, six, and daughter Lilah, three, as they dressed up as and Angelina Ballerina.

shared an image of her daughter Dylan-Jorge, 10, dressed up as a Minion in honour of World Book Day.

In a touching tribute, Louise Thompson revealed that she'd been contacted by a follower whose daughter Katie, who also has a stoma, decided to dress up as her for World Book Day, after reading her memoir Lucky.

Posting snaps of her outfit on Instagram, she captioned the post: 'I wasn't ready for this. When I received this video and then a selection of photos of a young girl called Katie dressing up as me for world book day I genuinely thought I might faint, and then retire. My job here is done. I'm not sure I could feel more proud in my career.

'I wasn't sure whether to share as it feels so personal but Katie and her mother are such legends and she's such a brilliant advocate for all the young people out there that struggle with a stoma bag (and to oldies like me of course), plussss it's world book day today so it felt too silly not to. 

'The idea of someone dressing up as me giving me credit as an author gives me major imposter syndrome but just WOW.

'Katie's mum sent me this video of her reading my book 'Lucky' a week or so ago and I've showed all my family members and watched it over and over in disbelief.

'Katie lives with a stoma. She's already navigated more hospital corridors and harder conversations than most adults ever will. 

'Listening to her read passages that came from some of my lowest moments carried a weight I hadn't quite anticipated. When I wrote Lucky, I didn't know who would find it, or when. You hope it lands softly somewhere it's needed.

'The fact she's chosen to dress up as me for World Book Day is a moment I'll treasure forever. I can't wait to show my son when he's old enough to understand. He's going as Paddington tomorrow, surprise surprise. I imagine most young children will go as innocent characters from popular children's books that have sold millions of copies.

'Katie, is choosing to break the mould. She has experienced more than most people double her age and that will offer her infinite wisdom for the future. Thank you to you and to your mum for sharing this with me. 

'And for the quiet advocacy you're doing just by being yourselves. It will help so many people. It was only today as I was walking around the Houses of Parliament that I had a conversation with a woman who had recently had a stoma surgery. It's more common than you might think. We are true warriors.'

The Heart Radio breakfast team also got in on the World Book Day action, dressing up as characters from the iconic Jolly Holiday scene from the Mary Poppins books.
