X Factor backlash begins after fans go online to complain
Fans went online to complain, with dozens backing axed teenager Amelia and calling for her to be given another chance.
Josh King tweeted: "Amelia Lily needs to come back", former News of the World journalist Dan Wootton wrote: "Cannot believe Amelia didn't go through. I don't agree with that decision. I think Amelia had so much potential."
Another fan, Ruth Payne, tweeted: "So disappointed in x factor this yr!! Dnt understand sending amelia home really disappointed!"
Amelia burst into tears after her mentor Kelly Rowland told her she was leaving.
Sporting a new pink hair-do, the 16-year-old student opened the show on Saturday with an energetic performance of Michael Jackson's Billy Jean.
Rowland said: "Amelia has an incredible voice, all four of my girls are so amazing, I just had to make a decision.
"But let me tell you something, y'all are going to see this girl everywhere. She has an incredible voice, she's confident, she's bold and she's young and the sky is the limit for her."
As the sobbing teenager walked off the stage, Rowland chased after her.
Each of the judges - Gary Barlow, Louis Walsh, Tulisa Contostavlos and Rowland - were forced to select one of the acts they were mentoring to send home.
The female judges both burst into tears as they delivered the news to their acts.
Contostavlos, who is nurturing the groups, said she made up her mind only half an hour before going on stage, adding: "You can't imagine how much of a hard decision this has been for me.
"I have spent hours crying tears and pulling my hair out over the decision because I have got to know all of you and you are all my friends and I can say that from the bottom of my heart."
She chose to send 2 Shoes packing after the pair failed to impress the judging panel on the first of the live shows.
Charley Bird and Lucy Texeira sang the Girls Aloud party track Something Kinda Ooh while in a pink convertible on stage.
Barlow commented that the performance was akin to "karaoke night in Romford".
Miss Texeira said: "We are just so proud that we made it this far, this whole journey has been amazing. We are the best of friends and we have become even closer."
Jonjo could be back on the frontline now his bid for X Factor fame is over.
The serving soldier, from Chorley, Lancashire, was given special permission by the Army to take part in the show.
Walsh said that it was a "really tough decision" to get rid of the 27-year-old.
He said: "This was not easy. I agonised about the whole thing. At the end of the day, I have to keep the person who I think the public are going to like the most."
He performed The Kinks' You Really Got Me on Saturday night but Barlow, who appears to have taken the helm from fearsome judge Simon Cowell, said he stuck out "like a sore thumb".
A slow rendition of Ticket To Ride by The Beatles failed to save James Michael from being kicked off the reality show. Walsh likened the 20-year-old from Cheshire to "a busker in Covent Garden".
With tears streaming down his face, James said: "I am just going to carry on with the music."
Saturday night's show had a peak audience of 12.7 million viewers, an ITV spokesman said.
The first live show was watched by an average of 10.9 million, while its reality rival Strictly Come Dancing was watched by an average of 8.7 million.
