Other clues that lead fans to believe that Cody is about to take part include:
Clue: “I was created by the digital age.”
Cody was discovered on YouTube by a Grammy-award winning producer, Sean Campbell.
Here's a few more:
“Growing up, I was surrounded by gold."
He was born on the Gold Coast to Brad and Angie Simpson, before relocating to Los Angeles in June 2010 to record music.
Clue: “I really care about the real world” AND “I’ve always been connected to the water.”
In June 2017, he was named the first United Nations Development Programme advocate for oceans.
Clue: "I headed East like a moth to a flame, but I soon realised others were controlling my program. I felt like such a clone! So I short-circuited the production line and I'm now very much my own robot."
He moved to America in 2010 to boost his career, but in 2014, he left his record-label, Atlantic Records, due to creative differences.
Meanwhile, Cody has been making headlines for his new relationship with Miley Cyrus. She took to the 'Gram over the weekend to defend herself for kissing Cody over an acai bowl in LA.
The 26-year-old singer feels like she was "slut shamed" for moving on after her split from her Australian actor husband, Liam Hemsworth, and most recently Kaitlynn Carter, ex-wife of Brody Jenner.
Miley also joked that Cody ticked off all the boxes on her list: he's 22, Australian aka her "type" and he has abs - can you blame the gal?
