The 'Body Coach' star and his partner Rosie Jones will welcome their first child into the world in just 10 weeks time.

He revealed on Instagram: "Hey everyone, I'm gonna be a Daddy [heart] This is the first time I've ever shared a photo of myself with Rosie.

"I've always chosen to keep my personal life and relationship private but with such an amazing new thing coming into our lives I thought it would be nice to share the news with you myself. We are both absolutely buzzing to be parents.

"We don't know the sex of the baby but it's due in just over 10 weeks time. #TheBabyCoach coming soon..!(sic)"

Though he's kept his baby news under wraps for some time, in January, the 31-year-old fitness expert admitted he's spent a lot of time thinking about the sort of parent he wants to be.

He said: "I think about this a lot. Like, will I put them in private school? I didn't have that and I turned out alright. I don't want my kids to be spoilt, I want them to learn the value of money and of working."

And Joe admitted he was keen to marry the former glamour model, but prefers to keep their relationship out of the spotlight.

And when asked if he wanted to get married, he said: "I think so. I've been with my girlfriend for a year now.

"She's definitely The One. But some things you have to keep for yourself. I live on social media every day, so the only thing I have that's private really is me and my girlfriend.

"I want to be successful, but I don't want to be famous."

The couple were first revealed to be dating in September 2016 when they posted matching vacation photos from Necker Island.

A source said at the time: "Joe and Rosie have been seeing each other for over two months.

"They have been trying to keep it quiet which is why they kept each other out of their posts on social media.

"But they are out on Necker Island as a couple. Rosie is actually the one taking the pictures of Joe and vice versa.

"They have had a perfect first holiday together. Joe's been referring to it as a 'celebration week'."
