The boyband will celebrate four years since first appearing on The X Factor with a one-off 90-minute special on Sky1, according to The Sun.
A Very JLS Christmas will see the group in an enchanted forest setting in front of 400 of their most loyal fans.
JLS will perform a selection of Christmas favourites and carols, alongside their own hits.
The special will air on Sky1 in December, with an exact airdate expected to be confirmed in the near future.
Michael Bublé brought back the tradition of popstars fronting Christmas TV specials with his own show on ITV1 last year, in the same vein as holiday specials from Andy Williams and Bing Crosby.
JLS will face off against Robbie Williams when they release their latest album Evolution on November 5.
