Hayley Millar, 19, is a music student and cleans toilets for a living — and when she belted out one of her own songs with the aid of her trusty acoustic guitar, the Balloch girl was given a thumbs up by judges.
She was one of the many hopefuls who queued for the chance to perform at the X Factor mobile auditions at the St Enoch Centre where those who impressed were given a golden ticket and a pass into the second stage.
Now Ms Millar hopes to swap bathrooms for the much more glamorous surroundings of the X Factor live shows.
She said: "I sang an original, one of my own songs called One Day.
"It was very nerve wracking but they must have liked it, I hope they did.
"This was my third time auditioning and I've got beyond this stage before.
"Hopefully I can go further this time.
"I clean men's and women's toilets for a living and I'm a student at the Academy of Music and Sound."
Another who impressed the judges was 17-year-old Zoe Brunton, from Carluke, South Lanarkshire.
She is a pupil at St Aidan's High School in Wishaw — the same school attended by former X Factor finalist Nicholas McDonald.
She sang In the Arms of the Angel by Sarah McLachlan and One Night Only by Jennifer Hudson. After being handed her golden ticket, she said: "I'm still so nervous, my legs are shaking. The judges said I was good but that I should pick a faster song for next time.
"I came last year but didn't get through, I think because I was too young and very nervous."
