Kylie's future on the show had been in talks for a few weeks now, as it was thought her forthcoming tour would clash with the show's schedule for next year.
Confirming the news on Twitter this morning (11 April), she said: "#Lovers, due to timing of my tour I won't be back next season for The Voice UK. Thanks to all who supported! Hope to see you on my KMO tour!"
The official BBC One Twitter account said: "Kylie has brought her own very special magic to @BBCTheVoiceUK and we have absolutely loved having her on the show."
Aussie pop princess Kylie joined series three of The Voice UK along with Kaiser Chiefs frontman Ricky Wilson. The pair replaced coaches Jessie J and Danny O'Donaghue, while joining original coaches Tom Jones and will.i.am.
The Voice UK final wrapped up last week, and viewers voted 19-year-old Londoner Jermain Jackman as the winner.
The BBC One talent competition has been a huge success this year, and Kylie has been credited with boosting its viewing figures.
Kylie, who released her 12th studio album Kiss Me Once last month, said in interview with The Mirror in March: "I'm touring this year and the timings wouldn't work."
But it was since reported that show bosses would try to work around Kylie's tour commitments to keep her on the show. The BBC has already commissioned another two series of The Voice UK.
