The HELLO! Online blogger took to Instagram to share the sweetest photo of her newborn son Buzz Michelangelo, who she welcomed into the world with husband Tom Fletcher three weeks ago.
In the colourful snap, baby Buzz is caught mid-yawn and seems ready to enjoy a nap as he scrunches up his nose and his eyes drift shut. The famous tot looks even cuter snuggled up in a bright orange Tigga onesie.
"Keeping mummy up all night is just exhausting…," wrote Giovanna next to the photo, which Tom retweeted to his 1.29million followers.
The pictures comes just days after Tom, 28, and Giovanna, 29, took Buzz out for his very first outing. The McFly singer decided to capture the moment by striking a pose in a shopping mall, one hand gripped tightly onto Buzz's pram and the other waved in the air.
"Our 1st proper outing," he captioned the image.
After the birth of his son on 14 March, Tom proudly changed his Twitter bio to "Dad!" and has been keeping his fans happy with regular updates of Buzz's latest movements.
One of Tom's most famous masterpieces was perhaps his video entitled From Bump To Buzz — which shows snapshots of Giovanna's belly growing throughout her pregnancy while Tom sings a brand new tune in the background.
The clip made it onto US TV and went viral, with stars such as Russell Crowe sharing it on the web.
"Erm... THE Russell Crowe just tweeted a link to Bump to Buzz.......... Amazing!" wrote an astounded Giovanna when she found out.
Tom's fellow bandmates have all met baby Buzz and shared their own snaps with the newborn. Last weekend, Harry Judd posted a particularly heart-melting photo of him cradling the sleeping baby, writing next to it, "Me and Buzz ❤️."
