'Late Late Show' host Ryan Tubridy told Voice UK star Lucy O'Byrne she "was robbed" in the final of the BBC talent series.
"I really did feel you were robbed," Ryan told Lucy as she appeared on his show earlier tonight.
Gracious Lucy insisted that winner Stevie McCrorie was deserving of the win in last Saturday's final and insisted she didn't feel "robbed".
She told Ryan she was still in shock over how well she did on the series.
"I still can't believe that the chairs turned," she told the host.
Lucy appeared on the first series of the 'Voice of Ireland' in 2012. She made it to Kian Egan's team and got as far as the 'Battles' round. Pat Byrne, who was on Bressie's team, subsequently won the series.
When asked about the difference between the Irish and UK versions of the show, she described it as "huge".
"I only got that far so I can't speak about the whole series but just the scale of it is what stood out for me.
"I think on any given Saturday, there were between nine and twelve million people watching The Voice UK.... almost three times the entire population of our country. That's crazy," she explained.
She also discussed the special relationship between her mentor, Black Eyed Peas frontman will.i.am and her Nana Rose, or his 'Hometown girl' as he dubbed her.
"I'm not sure when that relationship blossomed. I can't really remember when it first started," she laughed.
"But I remember that I when I walked into a room with him he would be like 'hey how are you' and the next question would be 'how's your nana'. Every single time. I think he met her at the battles. He came down to say hello and say congratulations."
She recalled how she was giving an interview backstage following her success on the 'Battles' and turned to a big TV screen. "And there was Will hugging my Nana. I was like 'hold on a second - Will is with my Nana Rose'," she laughed.
Will and fellow mentor Rita Ora turned for Lucy in the blind auditions. She opted to go with Will as she heard he was looking for a classical singer.
"I loved working with Will. When you watch him back on TV - it's edited a lot. He comes across like he only talks in metaphors which is not the case. He was really easy to have a conversation with. I got on really well with him.
"He's great in a rehearsal room as he's very passionate about what he does. He's very open in a rehearsal room. I found it very easy to talk to him about what I wanted.
"But he was so supportive. He was encouraging. So interested in what I was doing."
Since the show ended on Saturday, Lucy has been busy.
She's hopeful she will bring out an album soon, telling Ryan there are some offers on the table that she's considering.
