There are only three weeks left of The X Factor before the season finale and it’s going to be a double elimination for the next two weeks, so the performers are giving it their all. This week the contestants are performing songs that hit number one on the charts.

Fifth Harmony
Song: What Doesn’t Kill You Makes You Stronger
Judges Comments: LA Reid: I thought it was good but I wanted ground breaking. Britney: I thought the song worked for a group. Demi: this was probably one of the best performances you’ve given. Simon: What a fantastic performance you just gave. This is the first time I can see you in the charts.
