Ben was pictured arriving at the Press nightclub in London, where he joined runner-up Fleur East and former contestant Stevi Ritchie for one final celebration.
Creative director Brian Friedman and Xtra Factor host Sarah-Jane Crawford were also in attendance, but the judges were noticeably absent.
Former van driver Ben graciously thrusted both arms in the air as he posed for waiting photographers.
Yesterday, One Republic gave Ben the seal of approval after he used their track 'Something I Need' as his winner's single.
Ben released his rendition of 'Something I Need' on Sunday night, and it is currently Number One on the UK iTunes chart.
In fact, Ben has now taken an early lead in the race for the coveted Christmas Number One spot selling 75,000 copies of his single, according to data from the Official Chart Company.
Mark Ronson's reigning Number One single 'Uptown Funk' is currently just 23,000 copies behind Ben.
There's no rest for Ben now, who will be continuing a promo tour and attending a CD signing for his debut single today!
