Appearing on the May cover of InStyle Australia, the 33-year-old beauty 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.
The Think About You hitmaker 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 adds: '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.
