The Australian singer made her way to the studio in the early hours of this morning to join presenters Dave Berry and Lisa Snowdon.
Earlier this week, Kylie announced details of her new single, 'Into The Blue', which will be taken from her forthcoming album Kiss Me Once.
Speaking about her new single this morning (28 January), she said: "It's about love. Actually, it's about going into the future and not disregarding the past. Looking where you've been right and wrong and thinking into the future, which is kind of where my mind is set at the moment.
"I spent all last year working on this album and the fact that the first single is coming out is kind of mind blowing."
Spanish singer Enrique Iglesias and Grammy award-winning musician Pharrell Williams are just two artists who have worked on Kiss Me Once.
Speaking about Pharrell, Kylie added: "He's a dream come true because I've wanted to work with him for such a long time.
"I had two days with him and did two songs, one of which is on the album. It was amazing just to see him create a track."
Kylie has received positive reviews since joining The Voice UK for the new series, which kicked off earlier this month.
Kylie, who first rose to fame as schoolgirl Charlene Mitchell in Australian soap Neighbours, is enjoying her role as a judge on the talent show alongside Kaiser Chiefs frontman Ricky Wilson and veteran judges Tom Jones and will.i.am.
This weekend's show saw auditions from Adele's cousin Georgia Harrup, as well as Vicky Jones, who is the sister of McFly star Danny. Both female singers secured places on Tom's team.
Kiss Me Once, which will be Kylie's 12th studio album, will be released on 17 March. 'Into The Blue' is due for release on 9 March.
