Seann, who was the fourth act to be voted off this year's talent show, found love with a fellow singer at Bootcamp in the boys' category, who didn't make the live shows.
Although he is keeping the name of his new love top secret, Sean told Gay Times magazine that things are serious between the pair, revealing he now wants to get married.
Seann revealed: "When I was truly happy and started putting myself out there, he was like, 'You're amazing, you're hot'. And now I'm f**king so in love. I want to marry him."
In other X Factor news, it's been confirmed that Seann will join the rest of the remaining contestants on tour.
Despite leaving in the second week, Seann was chosen as a wildcard by the judges and was given the opportunity to join the live arena tour kicking off in February next year.
