The 45-year-old singer - who has six-year-old son Ethan with model and former partner Kris Smith - has admitted she is currently in a relationship with a new beau, but whilst she says she's happy with her partner, she won't reveal his identity.

When asked about her relationship status during an appearance on Australian radio programme 'The Kyle and Jackie O Show', Dannii - who was previously in a relationship with producer Adrian Newman - said: "I'm in a very happy, non-talking about it space. That's life ... I'm in a space."

Later in the show, host Kyle Sandilands attempted to get Dannii to reveal the identity of her partner again when he asked her who she would be presenting with at next month's TV Week Logie Awards in Melbourne.

He said: "I know you're not up there with Kris (Smith), the new bloke wouldn't like it."

The 'I Begin To Wonder' hitmaker dodged Kyle's clever questioning, however, and refused to give any further details.

Meanwhile, Dannii previously opened up about the "sadness" she felt at her older sister Kylie not having a family of her own, as she was always more maternal than Dannii.

The 'Put The Needle On It' singer said: "Growing up, it was Kylie who always wanted kids and I never really did. When my brother Brendan had his little boy, I hadn't a clue even how to hold him. I remember being really impressed by Kylie because she just instinctively knew what to do.

"When he was a bit older, she'd be the one rolling on the floor with him, making him laugh his head off and I'd be thinking, 'What do I do?' When I got pregnant I was completely shocked.

"But having a baby changed everything. Kylie has been incredible with Ethan. She just loves him - I love to see them together.

"[Not having her own kids is] a great sadness for her, it's a great sadness for me and it's also made me really understand how blessed I was to be a mother.

"Kylie wrote a song called Flower about how she feels about motherhood. It's so beautiful it makes me cry. But you just don't know what is going to happen in life."
