The 16-year-old blew us away with her self-penned audition song, which was so moving it even managed to turn the usually tough-as-nails Tulisa into a soft, gooey ball of goosebumps and tears.
Watch Digital Spy's interview with Ella Henderson below:
Henderson's life has been turned upside down overnight, with fans already covering and reworking her song and a huge following already developing on Twitter.
During a run of TV interviews this morning, Ella bumped into 2011 winners Little Mix, who gave the teenager some advice on how to get through the ITV1 talent show.
"Bumping into them was really, really nice. Their image is really strong, they look so beautiful together," said Ella.
"They gave me nice general advice on how to take criticism, how to be yourself, stay true to who you are and how you don't let people change you on the way."
The X Factor auditions continue on Saturdays at 8pm on ITV1.
