The musician looked on with joy as 12-month-old Buzz - his child with wife Giovanna - did his perfect looking plop on the floor of his house, and rather than be annoyed he had to clean it up Tom took to Twitter to share his excitement at the emoji-like faeces.
He tweeted: ''My son pooped a perfect little swirly replica of the poop emoji on the floor this morning. I felt rather proud (sic)''
Tom is obsessed with poop and he and his McBusted bandmate Dougie Poynter have written children's books about it, including 'The Dinosaur that Pooped Christmas', 'The Dinosaur That Pooped A Lot', 'The Dinosaur That Pooped The Past' and 'The Dinosaur That Pooper A Planet'.
To mark World Book Day on Thursday (05.03.15), the 'Obviously' singer urged his followers to send him photos of them dressed as the Pooping Dinosaur or even poops.
He tweeted: ''If you're dressing up like @PoopingDinosaur today for World Book Day then tweet us pics! Wanna see that poop (sic)''
