The Filipino four piece, made up of sisters Irene, Celina, Almira and Mylene, have been wowing crowds across the UK and Ireland over the past month.
Their set includes a number of tracks from the live shows last year, starting with a rousing rendition of Bang Bang before an on-stage costume change proceeds an equally belting cover of Ain't No Other Man.
The girls later return alongside Seann Miley Moore for their mash up of Fancy / Rich Girl before a third stint on stage sees them singing Sound Of The Underground and The Clapping Song.
4th Impact end their X Factor tour set by showing a "different side" of their talents with a touching version of I'll Be There.
Of course 4th Impact are far from the only stars on The X Factor tour.
The bill is headlined by Louisa Johnson and also includes Reggie n Bollie, Che Chesterman, Lauren Murray, Anton Stephans, Mason Noise and wild card performer Seann Miley Moore.
