Tom Jones and Script's Danny O'Donaghue join The Voice
Tom Jones and Danny O'Donoghue have been added to the coaching panel on The Voice UK.
O'Donaghue, who is the lead singer of The Script, says he is a "massive fan" of the show, which has already been successful in the US.
The pair join Jessie J and will.i.am, who were recently announced as coaches.
The UK series, which will be presented by Reggie Yates and Holly Willoughby, is due to begin on BBC One in spring 2012.
O'Donoghue is best known as the frontman of The Script, who have had top five hits in the UK with For The First Time and The Man Who Can't Be Moved.
The 31-year-old said: "I'm a massive fan of The Voice, so to be involved as a coach is amazing.
"This is a show unlike any other because it puts vocal ability first above all else.
"I look forward to putting my team together and battling it out with the other coaches to see who wins this unique, credible competition."
Sir Tom Jones began his career in 1965 with the release of his debut single It's Not Unusual.
He has sold more than 100 million records during his career, and has previously won the Brit Award for outstanding contribution to music.
The singer's most recent album, Praise & Blame, entered the UK album chart at number two last year.
Jones said: "I'm excited about The Voice and thrilled to be participating as a coach.
"This is a strong show, it's all about talent - but it's also exciting, competitive and compelling television."
BBC One controller Danny Cohen said he was "delighted" with the four coaches.
"Our line-up of Tom Jones, Jessie J, will.i.am and Danny O'Donoghue gives us mega-star quality, great musical range and musicians we know our audience love," he said.
