WESTLIFE'S Kian Egan will prove Brian Kennedy wrong with a "storming performance" on the Voice of Ireland.
And ShinAwil producer Larry Bass has revealed how he never had any doubts about the mentor's vocal ability.
"All the mentors are singing this weekend and the rehearsal went extremely well," he said.
"What people forget is that we follow a format on The Voice and we can only have people who are singers themselves as coaches. I've known Kian for many, many years and before he was ever in Westlife, he was in a band called Six Become One.
"They were a vocal act under Louis Walsh's management and at the 1988 Miss Ireland contest, which we filmed, they did an a capella performance and all of them were well able to sing, including Kian. He has nothing to worry about."
Sligo star Kian, whose vocal ability had been questioned by rival Kennedy, will take to the stage for the first time as his team goes up against those contestants mentored by rival Sharon Corr.
And he is expected to be cheered on by wife Jodi Albert, who gave birth to their first baby Kai just before Christmas.
It will be her first time at the Helix Theatre in Dublin as she travels down from their Sligo home to show her support for her other half.
Tomorrow night's show will open with a performance from all four coaches who have been rehearsing together all week, before 12 of the remaining 24 acts perform for the public vote.
TV hunk Niall Breslin, who's still the hot favourite to win the competition, will also be performing his new single Breaking My Fall live on the results show.
The second instalment of the programme will see the top four from each team moving directly into the next round of the live shows and it will then fall to Sharon and Kian to decide their fate and who gets the axe.
Presented by Kathryn Thomas, there are eight weeks remaining until the grand finale on April 29 when the overall winner of the coveted recording contract with Universal Music Ireland is announced.
In a first for Irish TV, the coming episodes will also see Eoghan McDermott, discussing the latest tweets and Facebook comments with the acts after they've performed on stage.
