It's the final episode of bootcamp on The X Factor 2014 tonight as the Groups take to the stage.

Although first up Simon Cowell must complete his Overs six chair challenge, choosing who to swap out for Jay James.

And once that decision is done, Simon still has to decide whether or not Fleur East and Helen Fulthorpe deserve a spot after their performances.

After Simon's top six are finalised it's on to the groups and first out are twin teens The Brooks.

Louis is reminded much like Cheryl that giving the 15-year-old's a seat cannot be undone.

Then we meet the first of two new groups: An EIGHT piece boy band made up of Reece, Tom, James, Jake, Casey, Charlie, Barclay and Chris. The boys all originally auditioned as solo artists and after being sent home at Boot camp, they were asked to come back and the judges put them together as an eight piece boyband

Their cover of Run by Leona Lewis is their first ever live performance together but does the risk of making such a big group pay off?

Duo Blonde Electric bring the fun next, singing I Love Rock and Roll before the Pow Pow Girls win over the crowd with Ain’t No Mountain High Enough by Diana Ross.

Overload's fans make themselves known shortly after as the five piece sing 9 to 5 by Dolly Parton for one of the six spots at judges' houses.

The second new group is out next: A five piece girl band made up of Abi, Abby, Saffron, Mimi and Leah.

They sing Somewhere only we know by Lily Allen but how do they compare to the competition?

Concept and Only the Young finish off the groups performances but leave Louis with some tricky decisions.

It all leads to a three way sing off between a trio of acts as the Irish music mogul decides just who gets his sixth and final seat.

The X Factor 2014 airs this evening from 8PM on ITV.
