Jessica Origlasso wants to "settle down and have children".
The Veronicas singer recently rekindled her romance with actress Ruby Rose but is upset the pair can’t get married because of Australia’s ban on same-sex unions.
She told Australia’s Daily Telegraph newspaper: "We cannot get married.
"I’m at an age now where I’d like to settle down, I want to have children. I like the romantic idea of that."
The 31-year-old star – who is joined in The Veronicas by her sister Lisa – recently admitted she and Ruby have always adored one another, even after they went their separate ways in 2008.
She said: "We adore each other. We’ve supported each other through the last eight years of our lives, personally and professionally we’ve really grown together."
And Jessica believes she has her band’s new single ‘On Your Side’ – which features her girlfriend – to thank for her rekindled romance with the ‘Orange is the New Black’ actress.
She explained: "We were talking about the music video, [Ruby’s] such an incredibly creative person. She connected very deeply with this song. We fell into being in it together and creating this characters who play out this quite dramatic love story.
"It sort of just happened completely organically, we didn’t see it coming – she’s just an incredible woman and have incredible and I feel incredibly lucky to know her."
The couple fuelled speculation they had reunited with a series of pictures on Instagram and Jess says they want to find a balance between sharing their union and protecting their romance.
She said recently: "When we first got together way, way back, it was hard to know how much to share.
"Now we are quite protective of what we have, so obviously being able to be open enough but keeping a lot of it for ourself is something that we’re very conscious of and I think it just depends on the people what you’re willing to share."
