Former coach of The Voice UK Danny O'Donoghue is reportedly suing X Factor's James Arthur.
James and his co-writers have apparently been hit with a lawsuit over his hit comeback song Say You Won't Let Go.
Released in 2016, the song went to Number 1 in the UK and has sold over 1 million copies.
It was James' lead single from his album Back from the Edge, which also went to Number 1.
But the song is now set to be the focus of a court battle over claims its similar to The Script's 2008 hit The Man Who Can't Be Moved.
It's also claimed (via TMZ) that James had approached the band for a meeting to discuss music before putting out the song.

Richard Busch from law firm King and Ballow told Billboard: "It’s widely known Mr. Arthur was dropped by his record label for public controversies, which caused a break in his career...
"It wasn’t until the release of ‘Say You Won’t Let Go’ that he achieved worldwide success."
The lawsuit asks for an account of streaming, distribution, publishing and touring revenue from the song plus damages from the alleged infringement.
Speaking to The Sun newspaper, James said: "It is a legal matter. Until we figure out how that’s going to play out, I’ve just got to bite my tongue a little bit.”
James won The X Factor in 2012 but was dropped shortly after the release of his debut self-titled album.
However following his 2016 return to music, he re-signed to Simon Cowell's Syco record label.
Last year, James revealed he was already working on his next album and said the music would be more happier.
"The new album will be more positive," James explained in 2017. "The last album is something that I had to do as I was in a dark space and I had to talk about where I went.
"It was a hopeful album still but moving forward it will be more uplifting music.
"I am happy now so I want to talk about being happy."
