Larry Bass of the show's producers Screentime Shinawil said of the upcoming series: "We are delighted to announce this year's coach line-up. It's a welcome return for two-time winner Bressie and Kian Egan. Kian is seeking his first win, although he came close before - Kian is determined to win this year!
"New to the coach line-up we have Úna Foden, who has done it all in the world of music, including entering shows like this. Úna stuck at it and has had a remarkable career with The Saturdays. Úna as a Tipperary girl will know exactly what it takes to get to the top.
"And finally, we introduce Rachel Stevens to Irish audiences as a coach. Rachel has also scaled the heights of the pop world, not only as a member of S Club 7, but also with her solo career, so we look forward to Rachel adding even more glamour to The Voice this year."
John McHugh, Head of Entertainment RTÉ, added: "I am thrilled that Úna Foden and Rachel Stevens have joined The Voice of Ireland and I know they'll be an amazing addition to the show. Both Úna and Rachel are talented artists with a string of hits and have the expertise to spot a star.
"It'll be interesting to see how Kian and Bressie will react, as competition between the coaches is bound to intensify this year."
