Haven't we seen you somewhere before? X Factor winner Louisa Johnson previously auditioned for Simon Cowell's Britain's Got Talent
She may be only 17 but it looks like X Factor winner Louisa Johnson has quite a bit of experience in the music industry.
According to The Sun Louisa auditioned for Simon Cowell's other talent show, Britain's Got Talent, and recorded two professional music videos with a talent agency.
The videos were made by Mad Management, which has worked with both The Saturdays and Ed Sheeran.
Louisa also attended the Urban Edge theatre school run by footballer Stevie Watts and his vocal coach wife Katie, who worked with Louisa on her amazing vocals from the age of 11.
In 2013, Louisa auditioned for Cowell's BGT, but failed to make it through. She was also approached by X Factor producers to enter the show last year, but turned it down as she was still at school.
A spokesperson for The X Factor told The Sun, "No-one has been given special treatment and everyone was judged on the strength of their performances."
Louisa triumphed over fellow finalists Che Chesterman and Reggie N Bollie last weekend to become the youngest ever winner on the show.
Reggie n Bollie, formerly known as Menn on Point, had also auditioned for Britain's Got Talent this year. They got through to the stage two auditions but did not appear on TV.
Meanwhile, Louisa's single, Forever Young, looks set to claim the number one spot in the official UK charts on Friday.
