Union J and Jade Ellis face elimination from The X Factor in tonight's third live results show.
Last night saw the remaining ten X Factor finalists perform live for the fourth time, singing songs with a Halloween theme.
This evening, Dermot O'Leary revealed that Union J and Jade Ellis had received the fewest public votes and would have to sing again.
On Saturday night, Union J performed a "safe" cover of Beyonce's Sweet Dreams while Jade performed Sugababes hit Freak Like Me.
It's the first time in the bottom two for both acts, and a big shock for Union J who have become one of the favourites to win.
Favourites to leave - Rylan Clark and Chris Maloney - both avoided elimination, while the bookies make Jade the favourite to leave in the sing off this evening.
In the sing off the pair will go head to head and the judges - Gary Barlow, Tulisa Contostavlos, Nicole Scherzinger and Louis Walsh - will decide which of the pair stays and goes.
Although if the first two weeks are anything to go by, they'll just send it to deadlock!
