The 49-year-old got dolled up as Tinker Bell from Peter Pan novel Peter and Wendy for her breakfast shift on Heart FM - and it seems many of her enthusiastic social media followers certainly believe in fairies.
Radio host Amanda wore the skimpy costume to mark the annual children’s event to celebrate reading and books.
But it seems many of the thousands of Instagram and Twitter followers who Liked, commented on and shared the new snaps of Amanda may prefer to judge her by her cover, rather than her literary appreciation.
Her green, strapless outfit included a lace-up, corset-style top and a skirt made of layers of petal-shaped fabric in different material.
She also wore a pair of wings to accessories her unlikely workwear, as well as a pair of silver heels.
Tinker Bell never looked like that in my books!
Amanda captioned her image on Insta: "It’s a #Tinkerbell kinda day #worldbookday."
She also shared another post of her larking about in her dress which also got hundreds of her gushing fans rather excited.
A short clip showed Amanda skipping down a corridor at Heart FM HQ, even though she didn’t look particularly light on her feet.
She captioned that post: "When you wish upon a star .. try not to crash into a wall #tinkerbell #worldbookday."
Plenty of the tens of thousands that viewed that footage were quick to comment what a good sense of humour Amanda has, particularly for not taking herself too seriously.
But many more seemed to flood her comments sections with emojis and remarks which suggested her Tinker Bell look may be appropriate for more adult concerns than young readers may realise.
Among the comments fit to publish on ED! were those from some of Amanda celeb pals.
Former Corrie actress Catherine Tyldesley wrote: "#casual x."
Good Morning Britain correspondent Richard Arnold added: "Ding dong."
Presenter Jenni Falconer, meanwhile, commented: "Love this!"
And ex Geordie Shore star Vicky Pattison said: "You are the cutest."
"You look STUNNING," remarked another fan.
And someone else echoed that thought, contributing: "What a stunner!"
Other followers noted how surprised they were that a fictional character from a children's story could grab their attention.
"Wow Cheeky Tinker Bell," one critic wrote.
Another keen reader added: "Tinker Bell has never looked so good."
And yet another person who confirmed a history of reading said: "Tinker Bell never looked like that in my books!"
Fellow presenter Jamie Theakston also got involved with the World Book Day efforts, as Tink's nemesis Captain Hook.
