MAFS AU: Evelyn Ellis and Duncan James confirm they are a couple

Married at First Sight Australia stars Duncan James and Evelyn Ellis have confirmed they are officially in a relationship.

Ellis uploaded a picture of the two of them together on Instagram, saying: "The cat is out of the bag, and yes, the rumours are true... Duncan and I are officially off the market!

"Can't wait to share my journey with you guys."

She had teased some news on her Instagram earlier this week, saying: "I've never been good at keeping a secret from the ones I love; I have something special to tell you."

In an interview with Nine news in Australia, Ellis confirmed the rumours the season 10 contestants had ended up together after the show had finished.

"This is Evelyn and Duncan's hard launch. It feels good to finally just say it, and it feels kind of exhilarating in a weird, freeing way," she told the outlet.

Ellis was matched by the experts with Rupert Bugden, but in the final vows, they decided to go their separate ways.

James was paired with Alyssa Barmonde, but brutally dumped her at the final vow ceremony, telling her: "Maybe it's our personalities, maybe it's our differing mindsets but either way the gap seems too big to bridge.

"I don't want to hurt you and I don't want to continue getting hurt, so I have to say goodbye."

James revealed he'd been hanging out with Ellis as they were virtually neighbours in Sydney.

"We started hanging out a little bit after the show. Everyone's sort of friends in the cast, and obviously me and you living in Sydney we probably hung out a little bit more.

"All of a sudden we went out on a couple of nights, and some of the warm fuzzy feelings happened in my stomach and I thought, 'What's this? How we going here?'

"Then... one thing led to another."

The relationship's been warmly received by fans on Instagram, with the coming out post gaining over 100,000 likes.

However, Ellis had turned off the comments on the social media post.
