Max, 21, released his new single overnight, a bouncy dance track called All The Way, featuring Carla Wehbe. The music video features a mystery blonde cavorting with Key on Fiji's Treasure Island.
In Woman's Day, in which Max poses for no less than 10 shirtless photos as well as the cover shot, Max hits back at haters who claim he's been living under the shadow of his father.
"At the start, no one thought I did anything. Everyone was always saying, 'Get a job!' I was actually at university, still working, being me ... but it pissed people off because they thought I sat at home, living off Dad."
In retaliation, he details his venture into making lemonade outside his parents' home, and says: "I love making money!"
He also admits to hating vegetables and eating a terrible diet that includes fast food four times a week.
But when it comes to his career as a DJ, Max admits he might always struggle to emerge from the shadow of his high profile father. He hopes his music is judged on its merits.
"I always laugh because even if I put something out that was actually made by amazing DJs like Steve Aoki or the Chainsmokers, I reckon people would still say, 'Oh, it's Max Key - this sucks'."
Max's previous singles have been heavily viewed, with Paradise gaining 798,388 views on YouTube, and Forget You gaining 165,703 listens on Spotify.
