The couple met more than three years ago and told Spy last year they wanted to start a family.
The pair have three fur babies, a French bulldog and two white Samoyeds, but Fatima Savea made no secret about her desire to become pregnant and the struggle the pair had faced.

"Julian is a father already and he would absolutely love a whole rugby team of children, but to some it comes easily and to others it's very difficult and unfortunately we are on the difficult side of things."
