Mario Falcone is one proud uncle.
The TOWIE star, 26, couldn't resist sharing the most gorgeous photos of his baby nephew Buzz Michelangelo Fletcher on Instagram.
Mario, who lives in his native Essex, travelled across London to visit his sister Giovanna and her McBusted star husband Tom Fletcher. The first-time parents welcomed baby Buzz less than two months ago, and ever since, Mario has been bonding wonderfully with the little tot.
One of the most recent photos the TV star shared was of baby Buzz lying down and looking up at his doting uncle. The newborn is wearing a personalised blue and white striped babygrow, which has his name embossed on the front on a cut-out star.
"Nephew and uncle time :)," Mario captioned the snap, in which he is seen cradling Buzz.
The beautiful baby is clearly taking after his cool uncle, as Mario demonstrated in another photo. The image shows baby Buzz enjoying playtime with his famous relative and staring back at himself in a toy mirror.
"Posing... Wonder who he gets that from!! Ha!" Quipped Mario.
The television personality was clearly sad to leave baby Buzz the following day, just before his departure. "Last cuddle! Now back to Essex!!" he captioned a heart-warming snap of him cuddling Buzz and stroking the newborn's hair.
Giovanna recently shared a touching post on her HELLO! Online blog, in which she described how she and Tom had waited for their baby's first smile.
"Hours have been spent cooing at him and pulling silly faces — trying to tease the corners of those cute little lips upwards, but all we'd received in return was a look of confusion and bewilderment," she wrote.
"There were even times when those looks boarded on disgust — bemused at how weird his parents were behaving," she added. "We weren't taking it too personally that he was failing to find us funny or pleasing… Perhaps we just weren't entertaining enough and he wanted us to raise our standards.
"He was a tough nut to crack — but we eventually did it. The three of us were chilling in bed, on a lazy Sunday morning, when Buzz granted us with his first delightfully gummy expression — seemingly happy with whatever his daddy had been talking about. I didn't manage to capture the smile, but this pirate impression came shortly afterwards. What a cutie!"
