Appearing on the May cover of InStyle Australia, she revealed that she's made a "conscious decision" to no longer talk about relationships.
"All I’ve kept saying is 'I’m single and I’ll let you know when I’m in a serious relationship.' And I will'," Delta said.
Delta also touched on how she feels about her thirties, saying she "loves it!"
"It’s really different. There’s so much more calm," she told InStyle. "When I got into my thirties, I owned who I was more. I stopped having people project who they think I am."
She added: "Maybe I’m just a little bit of a late developer."
The Voice is currently in its Blind Auditions stage, with Delta battling it out alongside fellow judges Boy George, Kelly Rowland and Joe Jonas.
