Katie Price and Coleen Rooney's children were leading the star-studded World Book Day transformations.
Social media was awash with a whole galaxy of stars showing off their children dressed as their favourite book characters.
Kieran Hayler made sure his kids he shares with the former glamour model were the best dressed at their school.
Bunny, five, transformed into Disney hit movie Frozen's Elsa and Jett, six, morphed into Captain America.
Dressed head-to-toe in their costumes, Bunny and Jett were naturals in front of the camera as they smiled for the picture taken in Kieran's front garden.
Coleen and Wayne Rooney got involved in the fun as they transformed one of their four sons into the cat from Cat In The Hat.
He wore a red and white striped top hat, a big red bow and a full face of feline-inspired make-up.
Rochelle Humes and her husband Marvin have only just started sharing pictures of their children on social media because their kids asked why they weren't appearing in their Instagram posts.
The former This Morning presenter was delighted to share her daughter Alaia-Mai's transformation into Matilda and Valentina's cute appearance as Bing Bunny.
Amy Childs worked her magic on her daughter Polly to bring to life Disney's Belle from Beauty and the Beast.
Polly was sweet in her yellow Disney gown and her golden locks tied into a top knot bun.
She wrote: "My real life Belle.️ Awww my darling princess her first ever #worldbookday2020 how beautiful does she look please stop growing polly."
Jacqueline Jossa also gave her eldest daughter Ella, four, an epic Disney transformation for her school day.
Ella was instantly recognisable as Jessie from Toy Story 2 with her quirky costume.
The devil was in the details as the little girl wore two plaits and a red cowboy hat.
World Book Day has become an annual event to celebrate reading and publishing.
