Ben Cohen and Kristina Rihanoff will marry at “some point”, the former rugby star has said.
The couple became parents to their first child together – a daughter named Mila – in June.
They met during the 2013 series of Strictly Come Dancing and became a couple the following year, after Ben split from his wife of 13 years.
Asked about tying the knot, the 38-year-old former England player told Hello! magazine: “I imagine we will get married at some point.”
Former Strictly professional Kristina, 39, said she wanted to be in better shape when she walks down the aisle.

“It’s not something that we’re ruling out. We will see what the future holds.
“But with a baby, it’s not something we’ve got time to think about at the moment. And I want to be in better shape on my wedding day than I am now,” she said.
She said her life could not be more different now she is a mother.
“I spent eight years dancing on Strictly but now I enjoy watching it from the sofa,” she said.
“It’s a different life and I wouldn’t want to swap it. When I wake up in the morning and Mila is smiling at me, it’s just the best feeling in the world.
“I was ready for a change in my life. It’s not unusual for dancers to leave it a little later to have babies because you can’t work on a show like Strictly and have a baby. It’s very, very demanding.”

Ben, who has twin daughters from his previous marriage, added: “Having a baby later on in life, we were both very set in our ways so it has been a big change for both of us.”
Russian-born Kristina revealed her pregnancy news during a stint in the Celebrity Big Brother house earlier this year.
