The 48-year-old pop star has broken off her engagement to Joshua, 29, and thanked her fans with an Instagram post this morning.
She captioned the shot of a sunset: "#lovers … Thank you for all your love and support throughout this recent chapter of my life. Thank you now for your love and understanding with the news that Josh and I have decided to go our separate ways.
"We wish only the best for each other as we venture towards new horizons. #thesunalwaysrises," she added.
The Can’t Get You Out of My Head singer met Joshua on the set of US series Galavant in 2015 and the pair later announced their engagement in February 2016.
It's been reported that Kylie suspected the British actor has grown close to Spanish actress Marta Milans.
