Italian tailor Mario told fans yesterday evening (10 April) that he was looking forward to spending some "nephew time" with Buzz.
Mario, who has recently launched new online clothing store Lafamillia, couldn't have looked happier as Buzz lay on his chest - so cute!
Mario couldn't stop gushing either and shared more photos of Buzz on Twitter and Instagram.
"Very proud uncle!! I love him," said Mario, before adding: "Seeing this little guy tonight was just what I needed! Uncle/nephew time! Night all xxx."
Mario's sister Giovanna and her McFly husband Tom Fletcher welcomed baby Buzz on 13 March.
This isn't the first time that Mario has been sharing adorable photos of Buzz, but seeing as filming for TOWIE is on a break, we guess he'll be spending even more time with his nephew now!
