She's originally from Sydney
Just like Liam, Maddison comes from Down Under. While the actor calls Byron Bay home, Maddison is originally from Sydney. "When I got [Dynasty], I was in Sydney," she said in an interview in September. "Sydney will always be home. It's hard to leave every time I leave. I don't want to."
She's been working in the industry since she was 6
Maddison's biggest role so far is as Kirby Anders on Dynasty. But she's been acting since she was a child - her first role was in the 2004 TV movie Go Big when she was just six. She's also worked alongside fellow Aussie, Nicole Kidman, in Strangerland and played young Anna Marcy in The Kettering Incident.
Though she has been modelling since she was a teen, in 2014, Maddison told i-d that acting was her first passion: "I see myself as an actor, I did it before I did modelling. I felt like it was always something I wanted to do."
"Acting is more challenging," she continued. "It's easier to say I'm better at modelling but the process is different. The preparation for acting is insane. With modelling you just do castings and stand there and leave. Acting is such an emotional investment. I hope I'm good at both. Modelling is less emotional effort."
She has a (really cute) dog called Poppy
Maddison listed "my dog and Australia and food," as the things that make her happy during a recent interview. Liam shares a lot of animals with his ex-wife Miley, so thankfully Maddison seems to be an animal lover too.
She's a Taurus and loves astrology
She's pretty hilarious on Instagram
A source recently said that Liam and Maddison share the same sense of humour, something evident on Maddison's Instagram.
