The singer - who is also a member of the newly-formed McBusted supergroup - has been keeping fans up to date on his preparation for the little one's arrival by posting photos on Instagram.
And although he is undeniably excited, it sounds like he is a little out of his depth at the moment.
Tom posted a picture of himself cradling a dummy and pulling a slightly bemused expression and wrote the caption: "I'm halfway through a baby first aid class...not a clue what I'm doing!"
We're sure he'll get the hang of it soon!
But the pop star does seem to be enjoying the shopping trips to baby stores and picking out cute accessories for his unborn child to wear.
Today (21 January), Tom uploaded a snap of a grey hat covered in red stars and said: "Been at Mothercare all morning getting the first bunch of baby stuff, my fave being this hat!"
Tom and Giovanna - who were childhood sweethearts - announced that they are expecting their first child together via an adorable, Halloween-themed video message last year.
However, they have yet to reveal whether they are having a boy or a girl.
Whatever sex the tiny tot may be, it will no doubt posses a love of music and may even join Tom on tour in the coming months!
In November, 28-year-old Tom mentioned that Giovanna is set to give birth just weeks before he and his McBusted bandmates hit the road for their first UK arena tour together.
He told the Mail Online: "I'll obviously want to spend as much time as possible with Giovanna and the baby. Maybe they can join us on the tour? We'll just have to work it out as we go."
