Stevi found himself in the bottom two with Jay following Saturday evening's Big Band-themed episode and the pair went head-to-head in the sing-off.
Despite both his acts being in the bottom two, Simon decided to send Stevi home over Jay while Louis Walsh also made the same decision.
However, both Mel B and Cheryl Fernandez-Versini voted to save Stevi, meaning the competition went to 'deadlock'. X Factor host Dermot O'Leary then revealed Jay had received the fewest public votes so would be shown the door.
After the result was announced, fans - and even celebrities - took to Twitter to tell of their shock.
Stevi has long been considered the 'joke act' of the ITV1 show and many felt he should've gone.
Last year's X Factor winner Sam Bailey simply tweeted: "OMFG". Big Reunion star Dane Bowers, meanwhile, added: "Pantomime."
Stevi also received messages from viewers, with one telling him: "I think you should go, sorry."
The hopeful then took to Twitter himself and replied: "It's cool, I understand x."
But despite the uproar, Stevi has also received support too. After the result was announced, Katie Piper tweeted: "Woo hooo @THESTEVIRITCHIE is staying! #xfactor."
Stevi will now join his fellow six remaining contestants next week, with the theme being Whitney Houston versus Elton John.
