The former van won the last series of X Factor in December 2014 and, as is now tradition, he's been booked to return to the show to perform his debut single, 'Second Hand Heart'.
Ben – who was mentored by Simon Cowell – scooped the X Factor title and Syco recording contract over Fleur East, who was also in Simon's category.
Both have now signed record deals.
Ben's debut single is 'Second Hand Heart' featuring original American Idol winner Kelly Clarkson. It's the first track from his debut album, which is released in November.
He'll perform 'Second Hand Heart' on Saturday night's live show, while Little Mix and Ellie Goulding will perform on Sunday's results show.
Ben will tour his album in the UK next year, kicking off a 16-city tour in April.
