The pop star posted his precious picture on Instagram earlier this week and appeared to tease his fans at first by pretending to finally announce the sex of the baby.
Next to the rather blurry black and white scan, he wrote: "It's a...foot!"
He then uploaded another photo, this time with the baby's scan cropped to appear next to an image of his own large foot that was covered in inkings.
As well as a smiley face wearing sunglasses and what looks like the letter 'Y', Tom has also paid homade to his new McBusted supergroup by writing the band's name below his ankle. And it seems pretty real!
Beside the two snaps, he added the caption: "Looks just like me, right?"
Last November, Tom and the rest of his McFly bandmates (Harry Judd, Danny Jones and Dougie Poynter) announced that they would be teaming up with Busted's Matt Willis and James Bourne to form the exciting new pop force to be reckoned with: McBusted.
Better yet, the boys also announced that they are touring this year and rehearsals for their first concert are already underway.
In between keeping busy with his band, Tom has been spending time with pregnant wife Giovanna and preparing for the arrival of their first child by attending baby first aid classes and shopping for cute little clothes.
