Jack Walton voted off X Factor
Jack Walton has become the latest X Factor contestant to leave the competition.
The 18-year-old from Yorkshire received the fewest public votes after he sang Leona Lewis's hit Bleeding Love.
He said: "I don't know where to start. It has been amazing, a world away from what I'm used to. I've just loved it."
Earlier in the show, Louis Walsh said of his performance: "For me you are a small-room performer."
Simon Cowell said: "You've got a future in the music business."
Jake Sims performed on the show following reports claiming he tweeted about drugs.
He appeared with fellow members of band Stereo Kicks to sing Backstreet Boys hit Everybody.
The 19-year-old was said to have posted messages about cannabis on Twitter last year before he auditioned for the ITV show.
Stereo Kicks were given positive feedback from the judges.
Mel B said: "I just love that song. You killed it boys."
The theme for the show was Fright Night, with all the acts singing Halloween-related songs.
Ben Haenow was first to perform, with a version of AC/DC's Highway To Hell which prompted Louis to tell him: "You are the real deal."
Mel B was also impressed, saying: "It made me want to rush home to my husband, it was that hot."
Lola Saunders appeared on the stage next to sing Crazy by Gnarls Barkley, which Louis described as "scarily good".
Fleur East earned lukewarm praise for her take on Michael Jackson's Thriller. Cheryl Fernandez-Versini told her: "One of the things I like about you is that you are an entertainer."
Jay James's rendition of Mad World came next, with his mentor Simon saying: "You are taking huge risks in front of millions of people and I want people to pick up the phone."
Andrea Faustini sang Take That's Relight My Fire in a bizarre gold costume including a painted face which Simon described as "one of the craziest things I've ever seen on this show".
Lauren Platt's verson of Dark Horse by Katy Perry was described by Simon as "a very, very good choice of song" .
A red-eyed Paul Akister performed Bat Out Of Hell by Meatloaf which surprised Louis. He said: "I wasn't expecting that."
But Simon said: "I think you've got to lighten up and start enjoying what you are doing." However, Paul hit back saying he thought the criticism was "unfair".
Only The Young came next with a take on The Monster Mash.
Simon said: "This is the first time I think I saw you as the group you really are."
Stevi Ritchie closed the show with Music Of The Night from musical Phantom Of The Opera and he received a standing ovation from Simon and Cheryl.
Cheryl said: "I absolutely adore you and I couldn't be happier that you got to sing that song."
