Jackie Thomas was crowned X Factor champion with her performance of the winner's single, It's Worth It, co-written by peermusic UK's Adam Argyle.

The 22-year old Kiwilead the voting polls for seven out of the ten weeks of the competition and won in Monday night's final.

Argyle collaborated on the track with DNA Songs, the songwriting and production duo of Anthony Egizii and David Musumeci.
