Andrea Faustini, Fleur East and Ben Haenow will contest this year's X Factor final following the elimination of Lauren Platt at the weekend.
17-year-old Platt lost out in the sing-off to Faustini.
Paying tribute to mentor Cheryl Fernandez-Versini, Platt said she was "the most incredible woman I have ever met in my life".
She added: "Thank you for giving me this opportunity and for sticking with me through this opportunity."
