PICTURES! See tonight's X Factor Six Chair Challenge as Boys and Groups sing

Here are all the pictures from tonight's X Factor 2018 Six Chair Challenge.

It's the third and final instalment of the tough stage that will determine who makes judges' houses.

Last weekend saw Ayda Williams and her Overs and Simon Cowell and the Girls complete their line ups.

Tonight, Louis Tomlinson continues with his Boys before Robbie Williams rounds things off with the Groups.

Performances from the Boys include drag act Thomas Poun, the soulful J-Sol and Dalton Andre Harris.

While singing for Robbie in the Groups are the LMA Choir, ATTY, Tre Amici and Misunderstood.

We also meet some groups for the first time, including The Squirrels, Harry & Danny, Lost Tiger, Sweet Sense, The Hewitts and VIBE 5.

Plus, there's new groups A STAR, made up of Aaliyah Robinson and Acacia K, and Panda & Burgandy, who were rejected by Ayda last week as soloists in the Overs category.

They'll be singing for their mentor, the rest of the judges and a live audience of 4,000 at Wembley Arena.

As always, all the acts will be wanting to secure one of six seats in their category at judges' houses. As acts perform, each mentor will swap and change who's sitting down. Only those left with a seat once everyone has sung will secure their place at judges' houses.

But this year introduces a new golden X twist that will see one act put straight through the next round. They will be placed in a safe seat and can't be swapped out for another act.

Louis used his last week on Brendan Murray, but Robbie still has a Golden X act to pick.

The X Factor airs Saturday 6th October 8:35PM on ITV. The series will then continue at 8PM on Sunday with the first round of judges' houses.
