Dannii Minogue has revealed that her sister Kylie subjected her to a Voice-watching marathon when she arrived in the UK.
The Spinning Around singer has joined the coaching panel of the latest series of the BBC singing talent show and recorded every episode while sister Dannii was in Australia, before making her watch them all back-to-back.
Dannii quipped: "She does a good spinning around."
She added to Digital Spy: "She had kept them all recorded for me, so I arrived into town and got to catch up. I did a marathon. Originally she emailed me a link, but it had expired by the time I got there. But it was cooler to be in London and see it as it is."
Dannii, who used to judge The X Factor in the UK and who is now on the Australian X Factor panel, said it was good to see the public take her big sister into their hearts.
"It's so nice to see the reaction to her. I arrived back in London and everyone was like, 'I love your sister on The Voice'."
But the 42-year-old singer insisted it was never the plan for her to join Kylie as a celebrity mentor for the Battle Rounds.
