Original X Factor judge Sharon Osborne is to return to the show for its 10th anniversary.
Simon Cowell has denied claims that his TV shows exploit people, whilst admitting there are moments that make him feel "uncomfortable".
A Pink tribute act who lashed out after a failed X Factor audition has lost her complaint against the show.
X Factor's Rylan Clark, who became the eight act to be voted off the show, has told Daybreak that he was ready to leave.
He added: "If I'd have won it, there wouldn't be an X Factor next year".
X Factor's Rylan Clark has told Daybreak that he has decided to sign off from Twitter.
He said: "By all means judge my singing, judge my performance, but when it starts to get personal, about my sexuality. It's just not on and I don't need to hear it."
X Factor's Ella Henderson, who made a surprise exit from the show after losing out to James Arthur in a sing-off, has told Daybreak that she "excited about life after the show."
She said: "I'm just so excited to come away from it. If I look back six to nine weeks ago, like who was Ella Henderson? I've got this amazing platform and I wouldn't have had it without the show."
Simon Cowell tweeted his shock at the departure of Ella Henderson from ITV's X Factor, he wrote:
Ella! Gone??? Unbelievable.From @SimonCowell on Twitter:
X Factor favourite Ella Henderson has made a surprise exit from the show after losing out to James Arthur in a sing-off.
The pair had found themselves in the bottom two after the public vote.
After her last act left the show, judge Tulisa Contostavlos, said on ITV2's Xtra Factor: "I don't know what's gone on. I'm shocked."
Tulisa also said she was disappointed that Gary Barlow's final act Christopher Maloney is still in the show.
On Saturday night's show, Henderson received praise from the judges after she sang a slowed down version of the Grease classic The One That I Want.
Gary Barlow told the 16-year-old singer that she had just put on her "best performance to date by far", while Louis Walsh exclaimed she was "electric", adding: "You are going to sell millions and millions of records Ella."
There are now no remaining females left in the competition.
Former X Factor contestant Amelia Lily, who was diagnosed with Type 1 diabetes when she was three years old, is backing the campaign.
She said: "I feel very strongly that every parent and carer needs to know about Diabetes UK's 4 Ts campaign.
"My symptoms included drinking a lot more than normal and going to the toilet a lot.
"I was very lucky as my nana realised what was wrong with me because my uncle had been diagnosed with Type 1 diabetes when he was 14.
"It's so important that anyone who looks after children - not just parents but teachers, carers and other family members - knows how to spot the signs of diabetes.
"So many children are still getting really poorly before they are diagnosed and I want to help put a stop to that."
