It's a third bouncing baby boy for popular UK actress, author and online personality Giovanna Fletcher and her husband, Tom, lead singer and guitarist for the band McFly.

The childhood sweethearts made the sweet announcement this past weekend, introducing their youngest son via Instagram on Saturday, one day after his birth.

"Welcome to the world Max Mario Fletcher!" shared Giovanna late Saturday afternoon, accompanied by an adorable close-up photo of her snuggling her newborn. "We can’t wait to get home and introduce him to his big brothers... they’re very excited!" Little Max will be joining the couple's two older children, Buzz, four and Buddy, two.

Proud papa Tom also took to Instagram this weekend to gush about the family's newest arrival, sharing a black and white photo of baby Max mid-yawn.

"We are all totally in love with him and can’t wait to take him home to meet his brothers," he captioned the photo, which already has over 400,000 likes. "WE HAVE THREE BOYS!"

Giovanna and Tom met when they were just 13 and wed in 2012 after Tom proposed at the theatre school they both attended together as youths. In 2013, they announced that they were expecting their first child and made headlines when they shared a black-and-white video titled From Bump to Buzz, featuring an original song by Tom and starring the parents-to-be as they documented Giovanna's burgeoning bump. To date, it has almost 15 million views.

Their second pregnancy announcement that let the world know that little Buddy was on his way was just as elaborate and adorable as the first. Using a video game theme, and starring the entire family, the Fletchers (plus Buzz) revealed that "Player 2" would soon be joining the game.

When the couple announced that they were expecting their third child back in March of this year, they continued with their tradition of video reveals, this time using a snowman theme. They made it clear, however, that they were not going to find out the gender of the baby, and the only thing that mattered was that the baby was healthy.

"I know that is the line that people sometimes use that they don’t mean," remarked Giovanna, via her YouTube channel. "But I do genuinely mean that."

The newest member to join the Fletcher clan also shares his name with his uncle (Giovanna's brother and UK TV personality Mario Falcone, who is also expecting a baby with fiancée Becky Miesner later this year) and grandfather (Giovanna and Mario's dad).
