The 65-year-old judge has mentored the Girls category this year and her remaining act Grace, 20, will battle boy band Rak-Su and Overs artist Kevin Davy White to be crowned the 2017 champion this weekend.

Grace has wowed the viewers and the judging panel - also comprised of Simon Cowell, Nicole Scherzinger and Louis Walsh - by performing her own songs on the live shows and Sharon is sure she's going to be a big star in the music business.

Sharon joined the 'Loose Women' panel on Monday (27.11.17) alongside Ruth Langsford, Jane Moore and Coleen Nolan who all predicted that Grace is going to do well.

Sharon replied: "I agree with that. She's gonna perform superbly I know that ... And she's so talented. I mean she's got, honestly, when people say they have hundreds of songs written she really has and she will keep sending me all these different songs and I'm like 'Where do they come from?' "

Sharon also revealed that Grace is going to sing more of her own tracks this weekend and one classic track to try and win the public's votes.

She said: "She's going to do three of her own songs and a classic one and the competition is really tough. When you see someone that you believe in so much and then other people agree with you, it's a great feeling, it really is. It really honestly blows me away when I see these young kids going up there, they have never performed in front of the huge audience before, usually they have done, you know, working men's clubs or pubs. So there they are in front of the camera singing live and I'm like how do you have the courage to go out and do it. I'm amazed by it."
