Married At First Sight's Jayden Eynaud hints he's going to be a dad in cryptic Father's Day Instagram post

Married At First Sight's Jayden Eynaud has offered a cryptic hint about his family plans.

The 28-year-old kickboxer was paired with Eden Harper on the hit reality dating show, but split with her shortly after the show aired.

And on Father's Day, his brother Mitch Eynaud, who is also a MAFS alum, shared a post to Instagram that suggested Jayden might be starting a family soon.

Mitch shared a tribute to his father, showing a picture of him alongside Jayden.

'Father's Day,' he wrote, followed by a love heart.

But it was another mysterious message that set tongues wagging.

Underneath Mitch's father, he wrote 'dad', but underneath Jayden, he wrote 'soon to be dad,' followed by a hush emoji.

Jayden has not yet publicly announced who he may be expecting a child with, or even divulged that he's in a new relationship.

Daily Mail Australia has contacted Jayden for comment. 

But the family plans are unlikely to involve Jayden's on-screen wife Eden, from whom the kickboxer parted ways earlier this year.

Eden, 28, who met her partner on season 11, confirmed the news on Instagram in April, after eight months together. 

'When I made the decision at final vows to be with Jayden, I really did that with the intention of it being forever,' Harper began.

'Jayden & I spent many months together after the experiment, Cub gained a dad and I gained a whole second family who I'm truly grateful for.

'I'm saddened to share that toward the end of the show airing, our relationship came to an end. The reality is, the person I chose, didn't choose me.'

'Whilst I'm disappointed that what you saw didn't translate in the real world, I will never regret this experiment, the people I met, the lessons I learnt and the growth it has had on me.

She concluded the post thanking fans for their support.

Later, Jayden released a similar statement, posting: 'Sometimes in life, things don't always go the way you had hoped for. 

'After the experiment, Eden and I went back to the Gold Coast and continued to enjoy living our lives together and getting to know each other every day.

'However, unfortunately, our relationship ended not long before the end of the experiment airing. 

'As sad as it is, I’m so glad I got to go through this with such an amazing woman and a beautiful son [DOG EMOJI].'

He concluded, 'You will both always have a second family on the Gold Coast'.
