Stevi's time in the competition came to an end during Sunday night's results show after ending up in the bottom two alongside Andrea Faustini.
Simon saved his act, with all other judges – Mel B, Louis Walsh and Cheryl Fernandez-Versini – choosing to save Andrea.
Speaking to the studio audience, Stevi said: "The whole experience for me has been an absolute dream.
"I just want to thank all the general public at home for keeping me in, and my best friend and mentor Simon Cowell."
Stevi was the second contestant to leave this weekend, as Only The Young bowed out of the competition on Saturday night after receiving the least amount of votes for the Whitney Houston versus Elton John themed evening.
Only The Young, who were mentored by Louis Walsh, found themselves the unlikely casualties of X Factor's surprise double elimination weekend, despite getting good feedback from the judges after singing Elton's 'Something About the Way You Look Tonight'.
Louis praised the group's achievements and advised them to "get a record deal", before saying that they will go on to be "successful pop stars".
During Sunday night's show, Labrinth and Take That took to the stage as guest performers. David Guetta and Emeli Sande performed on Saturday.
