PICTURES! X Factor 2013 final six groups perform in New York!

Here's a picture preview of this week's X Factor 2013 judges' houses, as the final six groups sing for Gary Barlow.

After weeks of auditions and last weekend's nail biting boot camp, just 24 acts remain in the fight to become this year's X Factor champion.

This weekend each judge will have to pick only three to progress through to the live shows which start later this month.

The six acts remaining the Groups category are Brick City, Rough Copy, Kingsland, Xyra, Code 4 and a new girl group, who are still without a name.

This week we'll see them fly out to New York in the States for one last challenge as they sing for a spot in the live finals.

Helping out Gary make his decisions and watching the groups' performances will be former X Factor star Olly Murs.
