Mario (who is Giovanna's brother) took to Instagram with the cute snap of the Fletcher household's new addition, but made sure to keep Buddy's face well out of view.
Instead, he went for the classic snapshot of Buddy's teeny-tiny feet, telling his 740,000 followers: "Look at how cute and diddy Buddys feet are #nephew #family."
They are pretty cute, right?
Fans were quick to comment on Mario's post, congratulating the reality star on becoming an uncle again.
His photo of Buddy comes after Mario tweeted his excitement at meeting his new nephew for the first time. Mario had gushed: "Gooooood morning!!!! Off to meet my new Nephew Buddy today #soexcited."
And ever the doting uncle, he made sure to arrive with gifts for both Buddy and one-year-old Buzz, treating the boys to some new shoes.
Mario showed off his presents on social media, prior to handing them over, and told his followers: "As an uncle it is not just my job to keep a watchful eye over my nephews... But to also ensure their trainer game is strong from day 1! #buzz #buddy #family."
It's never too early to have a killer wardrobe!
Tom and Giovanna first welcomed their second child on Tuesday 16 February.
Announcing his arrival, Giovanna had said: "What a beautiful day to be born... Welcome to the world Buddy Bob Fletcher. xxx #player2."
Tom, meanwhile, referenced the couple's adorable video game-themed pregnancy announcement, telling fans: "Player 2 has entered the game." Before adding: "Completely overwhelmed with love for our second son Buddy, and can't wait for him to meet his big brother. Thanks for the lovely messages. X"
Not surprisingly, the couple were inundated with congratulatory messages - including those from Tom's McFly bandmates.
Dougie Poynter tweeted: "Congratulations @tommcfly and @MrsGiFletcher on their second sprog Buddy! Love love love."
While Harry Judd (who became a dad himself recently to daughter Lola Rose) gushed: "Congratulations @tommcfly & @MrsGiFletcher on the safe arrival of Buddy Bob Fletcher! Lola can't wait to meet him! Buddy and Buzz."
