She left school to become a performer, but assured the judges that her ambition goes beyond singing to empty rooms in working mens' clubs. She credits her 85-year-old granddad - who used to sing in a band in his youth - as her inspiration.

She is a Barnsley FC fan, and was spotted taking in a game at their home ground this past weekend.

What did Holly sing in her audition?

Her show-stopping performance of Alicia Key's If I Ain't Got You wowed the judges, and brought her granddad to tears backstage. Check it out below.

After receiving a unanimous "yes" from the judges she strolled through the Six Chair Challenge, and she will be in Sharon's group for the Judges' Houses stage.
