Louis Walsh has said that he is "worried" about the health of X Factor finalist Nicholas McDonald ahead of tonight’s big live show.
Speaking about the 17-year-old Walsh said: "I am worried about the stress and strain on Nicholas.
"He has this serious heart condition. I worry about that for the weekend, honestly.”
The young Scottish singing is on medication for a rare heart condition known as Long QT syndrome.
In the interview with The Sun, Walsh added: "There is nothing we can do. He is working really hard - we are just going to give him some time off.
“I think his family are worried but we want him there in the final."
Walsh also confirmed to Digital Spy recently that Simon Cowell will "definitely" return to The X Factor UK.
