It was rumoured that the pair would appear earlier this month, and it was reported yesterday (May 17) that Cole was using Gwyneth Paltrow's personal trainer Tracy Anderson to help her work out ahead of the unconfirmed guest slot.
The BBC has now announced that the pair will sing during the semi-final results show on Sunday, May 27, stating: "It is the eliminations again and this time there is more at stake than ever... a place in The Voice UK live final. Eight artists remain, but only one artist from each team will make it through.
"As the drama unfolds, international superstar Kylie Minogue and pop princess Cheryl Cole will also be performing exclusively in the Voice arena."
Cole is currently working on her third studio album A Million Lights, and has reportedly teamed up with Wretch 32 for track 'Screw You'.
Minogue has announced plans to release a compilation of her greatest hits, The Best of Kylie Minogue, in the UK on June 4 and in the US on June 19.
The Voice UK continues tomorrow night (Saturday, May 19) at 6.30pm on BBC One.
