It's been a bit of a mixed start for all of the boys, with neither having fully got into their stride so far.
Union J struggled badly on the first live show, but managed to bounce back on Saturday night, with Nicole saying they "did everything right."
And of course, their huge online following have been working non stop to help keep them in the competition.
District3 meanwhile have a much more old school style, and their harmonies have won the judges over... apart from Gary Barlow.
The Take That star told them at the weekend: "Boys, I think you’ve had a really bad night tonight. The harmonies were off, when you watch this back you’ll be disappointed.
“The song choice was very dated and I think in the battle of the boybands, Union J have taken it tonight.”
Some may claim it was those comments that landed the boys in the bottom two this week, but fortunately for their fans they managed to avoid elimination and will fight on for another day.
Completing the line up of groups is MK1, who have been flying below the radar so far but have managed to avoid the bottom two.
