Mario, 27, shared a video of his sister Giovanna and Tom Fletcher’s little boy struggling to say his uncle’s name – and it’s adorable!
In the clip, Giovanna can be heard asking her son ‘Can you say Mario?’ But Buzz can’t, and he’s so frustrated that he starts to cry.
But mummy isn’t too disappointed, and tells Buzz: ‘It’s a tough one isn’t it!’
Author Giovanna, 30, recently told Closer that Mario takes his uncle duties very seriously, and even cried when he took his first steps.
She said: “He loves it, it’s really sweet. I sent him a video of when Buzz first started trying to walk and Mario messaged back saying ‘oh my God that made me cry’.
“He’s very much involved. He loves coming over and having Mario and Buzz time.”
Mario recently returned to filming for TOWIE, after being suspended for promoting slimming pills on social media.
During his break from the ITVBe reality show, the hunk spent time with his gorgeous girlfriend Emma McVey in Portugal and hung out with his new puppy Oscar.
While the snaps of him with the tiny pup are almost too much to handle, we’ll be glad to have Mario back on our screens.
