It was the first round of auditions from the brand new series, with the age limit this year lowered to 14.
Holly was one of the first acts to sing for the judges and also one of the youngest.
The 15 year-old pub singer from Barnsley said it has always been her dream to perform on The X Factor.
In tonight's show, she said to the judges: "I live at home with my mum and dad. They're psychiatric nurses so there's no singing in that area of my family.
"However my granddad is a singer and back in his youth was in a band. He just loves music like me. That's where I get it from."
Holly went on: "When I was younger I remember watching X Factor with my family, thinking 'That's going to be me one day'. I need to audition!
"The dream today is to make my grandad and my whole family proud."
In the audition room, Holly sang Alicia Keys' If I Ain’t Got You.
The powerful performance got her four yeses through to bootcamp.
Other acts on The X Factor 2017 this weekend included boy band Rak-Su, who are made up of Ashley, Miles, Jamal and Mustaf.
Then as auditions moved to Liverpool, we met 27 year-old plasterer Sam Black and mum of three Kayleigh Taylor who both got through.
Further successful hopefuls appearing in tonight's opening show were primary school teacher Jack Smith, Irish shop assistant Rwanda Shaw and Brazilian Elisangela Mahogany, who surprised the panel with her performance in the judges' room.
Plus we met duo Jack and Joel, a singing pair of pals from London who attended Oxford University together.
The X Factor 2017 auditions air Saturday and Sunday nights on ITV.
The next episode airs on Sunday, September 3 at 8PM.
