Louisa Johnson, who was mentored by songstress Rita Ora, has won this year's 'X Factor' competition. 

Through tears Johnson admitted that she is overwhelmed by the news and is genuinely grateful to have been crowned the winner: "I've imagined this day for so many years - you have no idea how much this means." The winner's single of 2015 is 'Forever Young'. 

Rita Ora also spoke to hosts Olly Murs and Caroline Flack, adding: "Can I just say thank you to whoever voted. Thank you to Louisa for being the most talented, hard-working and gorgeous winner of 'The X Factor'. Reggie 'N' Bollie finished in second place and they were mentored by Cheryl Fernandez-Versini. 

Johnson, meanwhile, will be on the 'Good Morning Britain' sofa tomorrow morning (Monday, December 14) to talk about her momentous win.
