KYLIE Minogue and fiance Joshua Sasse have confirmed their support for marriage equality in Australia as it continues to dominate political debate.

Minogue, a gay icon, has noted how “backward” Australia is on the same-sex marriage issue, stating that “the earth didn’t cave in” in other countries where it is now legal and that “love is love.”

Her actor fiance Sasse has been outspoken on the topic on his social media platforms, even comparing Australia’s slow progress on same-sex marriage with Mauritania abolishing slavery.

“He loves Australia,” Minogue said.

“He’s so adamant to fight for gay rights in Australia and it’s coming from the most genuine place. He just can’t fathom that same sex marriage hasn’t been legalised and of course I back him up on that, we are waiting for it to happen.”

Last month during interviews to promote his new US TV show No Tomorrow, Sasse was asked by journalists about his own bucket list.

“I would have a naked day in nature and have lots of lovely sex,” he said.

The quote was twisted by some outlets to be a reference to his and Minogue’s own relationship. When questioned on their age difference he noted “I love her, and that’s it. Anyone who has met her will attest, she is just the most unbelievable bundle of joy.”

He also compared his bride-to-be to the film Fern Gully.

“Do you remember at the end of the movie whenever the fairy touches something, the flowers sprout everywhere? That’s what Kylie does.”

Last week Sasse took to Twitter to note the Australian media focused on those racier quotes from his day of interviews, not what he had said about same sex marriage.

“I saw he was annoyed,” Minogue said. “I think they’ve mishmashed a bunch of things he said into something else. I haven’t seen the article, I couldn’t even bring myself to look at it it, it’d just annoy me.

“As far as what he’s said about me he’s very generous, I believe he said some very nice things about me which of course makes me go very gooey, but I don’t know what was written. He’d always be gentlemanly, if it has come across as anything other that that, he’s been misquoted.”

Minogue revealed she has been recording new songs to add to a reissue of her Kylie Christmas album, which originally surfaced last year.

The album, which made No. 7 in Australia, included duets with Iggy Pop, James Corden and her sister Dannii, as well as a new song written by Chris Martin of Coldplay.

“I’m working on various things,” she said of her musical plans. “We’ve got some really really good new additions to the Christmas album for this year. I have started work on new material, the way the year’s panned out I won’t have that much time to work on it but my brain’s working overtime.

“I’m so keen to get what’s in my brain out and turn it into what I hear in my head, make that a reality. So new music is really, consistently on my mind. I’ve opened the door and stepped into the room but I’ve yet to spend as much time there as I look.”

The singer also revealed she has recorded an original duet with Robbie Williams; the pair last worked together on 2000s anthemic hit Kids.

The duet has been tipped to feature on Williams’ new album, due later this year, with his new record label Sony.

“Where it’s going to go I couldn’t tell you, but it’s very good,” Minogue said.

However the singer did not rule out a future duet between herself and her future husband.

“That’s how we met, singing together on (US musical/comedy TV shot) Galavant,” Minogue said.

“Why not? A Christmas album would be a good format (for a duet). Don’t hold your breath, nothing’s happened yet, but I don’t see why it shouldn’t happen.”

Minogue fans can see a free exhibition of her stage costumes stretching back to 1989, Kylie on Stage, at the Arts Centre from September 21.

The singer donated some of her most iconic outfits from each tour, as well as items of memorabilia.
