During an interview with The Sun Herald, Cody discussed marriage, and how after six months of dating Miley, he's nearly ready.
"I believe in marriage, but haven't thought too much about that," he said.
"I am far too young to consider it, to be honest. I just continue to surround myself with positive women who inspire me and teach me new things every day."
In the interview, Cody went on to explain how Miley is his muse.
"She is creative and inspiring, fiercely independent and encourages me to be my own person, too. We are both creative individuals who support one another."
In October last year, the pair sparked engagement rumours for the first time after Miley showed off a custon-made ring with the initials, 'C.S' on it.
Cort Jewellery who designed the ring, revealed on Instagram that it was originally Cody's, which means he gave it to her.
Promise ring maybe??
"When you wake up and freak out to see @mileycyrus wearing the custom ring you made @codysimpson," read the post.
In March this year, Cody revealed to The Sunday Telegraph that he had some exciting baby news.
“I would like to return back in Australia for sure,” he told the publication about moving back home when he starts a family.
The star was asked about whether he would raise his family Down Under, to which he replied: “Absolutely, yes”.
“I miss Australia a lot. I would like to come back more. I will always have a home base in LA, but Australia will always be Number 1.
“LA makes a lot of sense for me for work but I will always be an Aussie.”
