Tom Fletcher and Dougie Poynter are releasing a new book called 'The Dinosaur That Pooped a Princess'.

The McFly stars - who co-wrote their first book, 'The Dinosaur that Pooped Christmas', in 2012 - revealed they will be back with a new children's tome in September.

Speaking at the Specsavers Bestseller Awards, powered by Nielsen Book at London's May Fair hotel on Thursday (25.01.18) - where they won a silver award for shifting 25,000 copies - they said: ''We are so excited to pick up this award for a quarter of a million sales of 'The Dinosaur That Pooped a Planet'! Thank you to all our readers who have come with us on our pooptastic journey!

''We'd also like to take this opportunity to announce a brand new 'Pooping Dinosaur' adventure coming this autumn. 'The Dinosaur That Pooped a Princess' will be published this September and this time our hungry dinosaur has his eyes on the land of fairytales!''

Meanwhile, Tom recently revealed he discussed his ideas for a musical with legendary Hollywood director Steven Spielberg.

The musician and author had a ''nerve-wracking'' video call with the 'Jaws' filmmaker to pitch his plans, and even received his seal of approval at first.

However, Tom was forced to postpone meeting with the iconic director in the US, due to a video commitment with his bandmates.

The 'Dinosaur That Pooped A Lot!' writer - who is joined by Danny Jones, Dougie Poynter and Harry Judd in the rock-pop group - revealed: ''I did a video conference call with him, it was the most nerve-racking experience of my life. It went really well and we had a call five minutes after to say he wants everyone to fly out to New York to meet him.''

The 32-year-old singer had to turn down the once-in-a-lifetime meeting with the 70-year-old Hollywood star, and despite his sister, Carrie Hope-Fletcher, and cast heading out to meet Spielberg, he ultimately decided that it wasn't for him.

A gutted Tom said: ''My sister and all the team flew out without me. I was getting text updates and was so bummed out.

''He's not going to direct the project. He wanted to but it's a complicated story. Hopefully, one day it'll get made.''
