Author Giovanna gave birth to the couple's second son, Buddy Bob, on Tuesday, 16 February.
There's been no photo of the little lad yet. Instead, Giovanna announced the new arrival by sharing a photo of a sunny blue sky, saying: "What a beautiful day to be born... Welcome to the world Buddy Bob Fletcher. xxx #player2."
They're already parents to son Buzz.
Meanwhile, McFly singer Tom confirmed the arrival by saying: "Player 2 has entered the game." That's a reference to the YouTube video Tom and Giovanna created last year to announce the pregnancy.
He later added: "Completely overwhelmed with love for our second son Buddy, and can't wait for him to meet his big brother. Thanks for the lovely messages."
Tom, 30, and Giovanna, 31, announced in September that they were expecting a second child, using a creative YouTube video. It saw Tom bringing an old computer console down from the attic to play. Their son Buzz was selected as Player One… Player Two showed as 'Loading' before the camera panned to Giovanna's stomach.
Giovanna's brother is ex-TOWIE star Mario Falcone.
Congrats to Tom and Giovanna!
