The Australian singer, 45, will appear in the next series of the BBC1 singing show alongside Sir Tom Jones and will.i.am.
Both Danny O'Donoghue and Jessie J quit the programme at the end of the last series, so there is still a big red chair up for grabs!
The BBC announced the news about Kylie's appointment in a tweet this morning (11 September), saying: "That's right, @kylieminogue will be spinning around as a coach on @BBCTheVoiceUK series 3 with @RealSirTomJones & @iamwill. #TheVoiceUK."
The Beeb continued: "The remaining coach for the new series of #TheVoiceUK will be announced in due course."
Kylie has had a hugely successful career spanning four decades, so no doubt will be able to offer the hopefuls some great advice and guidance.
Her sister Dannii Minogue is very experienced as a TV judge, having starred on The X Factor and X Factor Australia, not to mention Britain & Ireland's Next Top Model, so we're sure she can offer Kylie some tips too!
