Vincent and former flight attendant Susan are already parents to a four-year-old son named Luca.
"He's absolutely gorgeous," said Vincent. "Susan, Luca and I are over the moon."
"Luca is very excited to have a younger brother," added the proud new dad.
The happy couple announced the exciting news of Susan's pregnancy exclusively to HELLO! in April, and revealed that they had struggled to conceive their second child.
"There was a big chance that we couldn't have any more children," said Susan. "It's a miracle really – a blessing. I was on the verge of going on medication to help me conceive when I found out I was pregnant."
"We're very happy," added 34-year-old Vincent. "We're very excited - I'm the happiest dad."
The couple, who briefly split up before Luca's arrival, said they were closer than ever as they prepared to become parents again.
"There have been a lot of obstacles and Vincent's work takes him away so much," said Susan. "But we've managed to overcome everything and as a result we've grown stronger.
"We have the same values. In some ways, we really complement each other. In others, we're very different. And at times we drive each other mad, but it just works.
"We have a very strong relationship. I think we could get through anything, really."
