The reality star might have just endured a long flight back from Miami, but that didn't stop Mario catching up with baby Buzz for the day.
Reunited at last, Mario posted a very cute snap of himself and his nephew.
In the picture, the 26-year-old can be seen planting a kiss on Buzz - his sister Giovanna and McFly's Tom Fletcher's son - as he stares wide-eyed into the camera.
Captioning his photo, Mario said: "Best way to get through jet lag!"
Well, a play date with a one-year-old will certainly keep him awake, that's for sure!
The Essex boy's latest photo comes after Mario recently enjoyed a holiday in Miami, where he was visiting British lingerie model, Emma Jane.
Lately, Mario has been pictured getting very close to Emma - sparking speculation the pair are dating.
Despite the long distance between the two, it seems romance could be on the cards as Mario has been referring to Emma as his "wifey" alongside his snaps.
Proving the feeling is mutual, Emma has been labelling Mario her "lover" on her own social media accounts.
Sound like they're already quite smitten to us!
Could this mean Mario is now off the market, then??
While he was out visiting his latest love interest, Mario was joined by his pal Ricky Rayment for a wild night out.
Already in the States, Ricky had been staying with his family in Florida following his split with Jessica Wright.
After Jess ended their relationship, Ricky said he needed to leave Essex to clear his head.
Before his trip away, Ricky told the official TOWIE website: "I can't wait to get away and spend time with my family, clear my head, let the dust settle and hopefully come back to Essex when I'm not hated anymore."
