Spencer shared a sweet snap of the couple and wrote: "WE'RE HAVING A THIRD BABY!!!"

"If you'd have told me a few years ago that by the age of 33 I'd have three beautiful children with the woman of my dreams I WOULD have believed you because that was always the plan….

"Having said that I feel fortunate every day for what we have. Family is EVERYTHING."

Vogue added: "It'll be the more the merrier."

Spencer had previously told MailOnline: "Both Vogue and I love children. We can't wait. We consider ourselves very lucky to have grown our family as quickly as we have.

"It was always the plan for us to move quite quickly in that regard. We're full of joy and excitement.

The showbiz duo then appeared on The Six O'Clock Show in January, telling Martin King and Una Healy: "It happened quite early, pretty much as soon as she was pregnant… we haven’t really thrown anymore into the mix, as far as I’m concerned we’ve had the chat."
