After not performing as well as he hoped at Judges' Houses, it was touch-and-go whether Simon Cowell would take Jay through to the live finals with him.
But after sleeping on his decision, Simon decided to give Jay another chance and the former serviceman is determined to give it everything he's got.
Admitting that the live shows are his last chance to make it as a singer, Jay said: "I've dedicated my last few years to this and I've worked hard. I've not achieved what I want to achieve yet. If I don't do that now, I kind of need to move on and be a provider for my family. And get a day job."
But not moving on just yet, Jay is preparing to battle it out with 11 other hopefuls to take the X Factor title.
After impressing not just Simon, but Louis Walsh, Mel B and Cheryl Fernandez-Versini in his first audition, the 31-year-old was tipped for big things by the panel.
After his heartfelt rendition of Coldplay's 'Fix You' during the arena stages, Simon dubbed Jay as the "one to beat" thanks to his passionate and moving performances.
On being an emotional performer, Jay said: "I'm not a person who sings just for the sake of singing. I couldn't ever sing karaoke."
He added: "I want to sing and mean every word I'm singing. So I do sometimes come across as very emotional but I do always try and bring it back before it goes too far."
Jay joins Ben Haenow and Fleur East as Simon's finalists heading into the live shows.
