The House Husbands actor is currently based in Australia while Goodrem is celebrating her birthday over in Los Angeles. In September, Hugh spent some time with Delta in California, posting this photo of the duo kissing in a pool.
Following the post, Hugh was asked about his relationship with the Born To Try singer during an appearance on The Morning Show.
"Any guy that snaps Delta up would be incredibly lucky. I'm sure she has a whole line. But look, maybe one day we will get married, who knows? You never say never!" he responded.
Despite fans hoping there is more to the rumours, the couple insists they're just good friends.
"We see photos...and we go, 'Okay put a ring on it, have kids, let's get this next chapter going,'' Hugh confessed to host Larry Emdur.
"We talked about it. I just don't think so. I do love Delta, I love her so much, she is one of my dearest and best friends...but that doesn't necessarily mean that there's anything more than that."
