The McFly singer later shared another photo of the mum-to-be lying on a hospital bed ready for her ultrasound scan. Giovanna appeared to be in an excitable mood and beamed for the camera while she waited to get a glimpse of her second child.

The couple are not the only ones excited to meet the new arrival; HELLO! Online blogger Giovanna recently revealed that Buzz is happy about having a baby brother or sister on the way.

"Buzz knows that there's a baby coming," said Giovanna. "The other day he was crying at around 4am and so he crawled into our bed and I said to him, 'Do you want to cuddle baby?'"

Scan time!

A tearful Buzz then hugged his mum's growing bump, showing that he understood the baby was inside.

"He understands the concept of a baby because some of my friends have babies and he knows they're called babies," said Giovanna. "But I think he thinks the baby will just go away when my bump does!"

Tom and Giovanna announced the happy news that they are expecting their second child together with an incredible video in September. Giovanna has been keeping fans updated with her progress throughout her pregnancy, admitting that she isn't winding down her busy schedule just yet.

"The lead up to Christmas is scheduled to be fairly manic with writing my fourth novel, promoting Dream a Little Christmas Dream and filming for Lorraine," she wrote in her weekly blog for HELLO! Online. "Oh wait, did I mention vlogging, blogging, being a wife, mother to a toddler and getting ready for our next bambino to arrive?"
