The 22-year-old Australian actress, who is now based in Atlanta, US, also said that she "never pursued fame to be famous" weeks after pictures of the duo kissing went viral worldwide.
Maddison and Liam, 29, were first spotted out together in New York City back in October, just weeks after his split from his wife, Miley Cyrus.
At the time, they were seen holding hands and enjoying a meal together while out in the West Village neighbourhood.
"As a model or as an actor when you are successful in those industries, fame eventually becomes a part of it and so I just see it as being part of the job," she told the publication.
"But it’s never been something that I’ve outwardly pursued."
Meanwhile, Liam's 'thirsty' Instagram snap has caused speculation that the star may actually be back on the market.
After a brief social media hiatus, on Sunday the hunky Hunger Games star shared a very cute black-and-white photo of himself looking adoringly at his beloved furry friend, Dora.
"@hemsworthluke captured this moment of me and my best friend Dora. Good god I love this dog," Liam captioned the Instagram post with his gorgeous pooch.
His close friend and fellow actor, Adan DeVine, was one of the first to recognise what the photo was doing to all of us.
"Thirst TRAP," his Isn't It Romantic co-star commented to which Liam adorably replied: "I just googled thirst trap. 100% true."
