Sam Bailey has been dropped by Simon Cowell's record label Syco.
The singer will not have her contract renewed, despite only winning the show 14 months ago.
Bailey confirmed the news on Twitter, telling followers that she was happy and had exciting plans.
The singer triumphed in the tenth series of the competition, later topping the charts with her single 'Skyscraper' and then with her debut album The Power of Love.
The Power of Love, which was later repackaged with extra songs, was 2014's fastest-selling album.
