Union J split the X Factor judges tonight with a 'safe' performance on the latest show.
The boys performed Sweet Dreams by Beyonce for tonight's Halloween themed fourth live show.
Nicole Scherzinger said: "Well boys, I thought that was absolute perfection. I thought it was brilliant. It was simple, it was beautiful, we asked for harmonies and energy last week and that's what they gave us."
Tulisa added: "I think the vocals were really good tonight, you did a really good job but my issue is that you played it a little bit safe. I thought you could've done something a bit more exciting."
Gary Barlow commented: "For me, it was safe. Surprise us, guys, come back with something different, change it up."
Louis Walsh said: "I believe in this group so much, the potential in you four boys is amazing, you could be the next big boyband."
