She wowed the X-Factor judges at her Wembley Arena audition by singing James Brown's It's A Man's World.
Molly has already made a name for herself in the North East with her powerful vocals competing in Unstoppable UK, Open Mic UK and Metro Radio's Big Audition.
Before her audition, she said: "I always go to my nana's on a Saturday and Sunday to watch The X Factor as me and my nana just love singing."
Following her successful audition, she also gained a seat during the Six Chair Challenge after Simon chose to give her a seat.
