Ella moves Tulisa to tears

This weekend, Gary Barlow, Louis Walsh, Nicole Scherzinger and Tulisa are set to select the acts they deem worthy of the live shows.

Gary is in charge of the Overs, while Louis has landed the Groups. Nicole is helping the Boys, while Tulisa takes care of the Girls - including Belfast teen Jade Collins.

Ella famously progressed to the Judges' Houses stage of the TV talent show after giving a slowed down version of the 1998 hit Believe, which moved Nicole to tears - and won the admiration of Cher herself.

In Saint Lucia, the 16-year-old is seen belting out 'I won't give up' by Jason Mraz - and Tulisa is getting teary behind her sunglasses.

Meanwhile Essex model Rylan Clarke is seen delivering his version of Rihanna hit 'We Found Love for Nicole and RnB artist Ne-yo in Dubai, while it could be bad new for songwriter James Arthur. Nicole tells him: "I just don't know if this competition is for you."

Louis Walsh brought an extra group in Las Vegas after trio Rough Copy exited the competition.

He said he found it difficult to choose between two groups to fill their space left by Rough Copy.

"In the end I invited boyband Triple J to come to Judges' Houses, but still felt that as I'd lost such a strong group in Rough Copy that I wanted to make sure the category was the best it could possibly be.

"I asked Gary, Nicole and Tulisa if they minded if I took a seventh act. They were happy as they felt they'd got the right six acts for their Judges Houses trips so I asked Times Red to come along and they said yes."

And Triple J got an extra member when Louis asked George Shelley - who was booted out of boot camp - if he would like to join in the band to become Union J.

But will Union J make it to the live shows? "There are other boy bands in this competition and they have the edge on this group cause they have been together longer," Louis tells the boys.

The X Factor is aired on Saturday at 8pm and Sunday at 7.40pm on UTV.
