X Factor 2016: Watch as Irina Dedyuk STRIPS at the six chair challenge

Here's a first look at The X Factor 2016 six chair challenge as Irina Dedyuk takes to the stage.

After working her charms on Simon Cowell in the auditions, Irina returns and puts on quite the display at Wembley as she whips off half her clothes half way through the performance.

Singing Mamma Knows Best by Jessie J, will Irina get a seat into the next round? You watch a preview of her performance above but the results will have to wait until Saturday!

By the end of this weekend we'll know just who's through to judges' houses as the acts in each of the four categories are cut down to just six apiece.

At the end of last Sunday's bootcamp episode, for the first time this series, the contestants were split up into their categories and each given their mentor for the rest of the show.

Simon Cowell is in charge of the girls, Nicole Scherzinger has the guys, Sharon Osbourne is with the over 25s and Louis Walsh - gasp - has the groups.

In the six chair challenge the acts in each category will perform one at a time with their own, hopefully winning, song choice, singing for all the judges and a live audience at Wembley.

It'll be their first time in front of a crowd on this years show and while those watching on will have plenty to say, as will the judges, it'll be each category's mentor that has ultimate power.

They'll decide who to place in a seat, representing a spot at judges' houses and they'll also have to decide who to switch and swap as the performances continue.

The X Factor 2016 six chair challenge airs Saturday from 8PM on ITV and continues Sunday night at the earlier time of 7PM.
