Seventeen-year-old Essex-born singer Louisa Johnson auditioned for the twelfth series of The X Factor, performing The Jackson 5's "Who's Lovin' You" to great acclaim (here's the video).

She made it through the X Factor rounds getting to the final and was crowned the winner when she beat Afrobeats duo Reggie 'N' Bollie with her cover of Bob Dylan's Planet Waves track "Forever Young." Louisa Johnson was the first winner in the Girls category since Alexandra Burke in 2008, and the youngest champion ever, overtaking Joe McElderry, who was 18 years old when he won in 2009.

Louisa Johnson released a cover version of "Forever Young" as her winner's single on December 13, 2015, immediately after being crowned the X Factor 2015 champion.

Louisa Johnson recorded the lowest chart entry for an X Factor winner's first single when the song debuted in the UK singles chart at #9.
