Tom Daley and filmmaker husband Dustin Lance Black are expecting their first child.

The happy couple revealed the news on Instagram, delighting their fans with a picture from the baby scan.

And a spokesman for Olympic diver Daley, 23, told the Press Association: “Tom and Dustin are thrilled to share that they are expecting their first child in 2018.“

The couple wed last year at an event with 120 guests.

On Wednesday, Daley posted a picture of the couple holding up to the camera a black and white image from their baby scan.

And the father-to-be told his followers: “Happy Valentine’s Day!”

His husband posted another photograph on Twitter.

“A very happy Valentine’s Day from ours to yours,” he wrote with an emoji of a family-of-three.

The couple got engaged in 2015, making the announcement in The Times newspaper.

Daley previously came out as gay in a YouTube video in which he said he was “dating a guy and couldn’t be happier”.

And he spoke last year about wanting children.

“We’re not planning to have children immediately, but we do want them in the future,” he told the Daily Mirror.

“I’ve always been a ­family person so I’ve always wanted kids, and I know Lance does, too. I don’t know how many – an army of kids, a whole diving team.

“We’re both lucky to have supportive families and we want to share that with our own children.”
