Ronan Keating and Storm Uechtritz are considering trying for a baby.
The 37-year-old singer - who has three children, Jack, 15, Missy, 13, and nine-year-old Ali with his ex-wife Yvonne - and the Australian TV executive have already discussed having another child and the 32-year-old beauty has admitted it is a "possibility".
She said: "We've talked about having a baby and it is a possibility for us, yes.
"We'll see what the future holds."
Storm cannot quite believe how easy being a step-mother to Ronan's three children has been because she expected it to be a "really difficult" challenge in her life.
She added to HELLO! magazine: "It hasn't been difficult at all, I'll be honest.
"The kids are amazing, incredible little souls, all three of them, and they've just been so welcoming.
"I pinch myself all the time. This should be a really difficult situation let's be honest, it generally is - but it hasn't.
"It's just been incredible and it fills my heart with so much warmth because even though they are not my children, I get to spend my life with them and they fill me with so much laughter and happiness."
The couple spend a lot of time in Australia, with Ronan working on 'The X Factor' Down Under, but the pair are due to move to London soon and Storm revealed they are also going to set up home in Ronan's native Dublin next year.
She said: "It's going to be great to be in London closer to the children and then next March, we're planning to buy a house in Dublin to be even closer to them."
