Viewers can throw a lifeline to one of the four acts who were ditched from the show by their own mentors, with 2 Shoes, Amelia Lily, James Michael and Jonjo Kerr in the running.
Now ITV and show producers talkbackThames and Syco have said the profits — amounting to at least 22p per call — will go to Help For Heroes.
None of the four ejected acts has so far faced a public vote, but show bosses decided to bring them back to plug the gap left by Frankie, who was axed from the show on Tuesday after he broke show rules by boasting about cocaine use.
The winner of the phone vote will return to the X Factor on Saturday night to sing alongside the remaining wannabes to perform either a Queen or Lady Gaga song.
X Factor judge Gary Barlow has admitted he feels responsible for Cocozza going astray.
Barlow said he feels a “level of responsibility” for Cocozza’s departure and also blamed fellow judge Louis Walsh for giving the 18-year-old negative comments last Saturday night.
In a press conference announcing the new voting twist, Barlow said: “I do feel a level of responsibility towards him but unfortunately I can’t follow him around all week.
“We try and take care of them while they are in our company. I said to him on a regular basis ‘You are a young guy, have fun but work hard at the same time.’
“We have all played our part in what has happened with Frankie and I don’t think any of us are guilt free in that.
“Especially as I am sat here with all of the press, we have all encouraged Frankie not only to be good but to be bad as well.
“We have enjoyed it and written about it, the show has enjoyed the publicity about it, but it has gone too far out of control for us as a show to have him still on here but I do feel a level of responsibility.”
When asked about what led to Cocozza’s behaviour, Barlow said: “I read messages, whether they were online, in the newspaper or on Twitter and they were all telling him he is not good enough.
“And the audience booed him on Saturday so I can kind of see where his life has led to in the last seven days and I don’t feel good about it at all and I don’t think anyone who has contributed to it should.
“I don’t want to isolate it to an incident but I felt Louis your comments to Frankie on Saturday night weren’t encouraging.”
Walsh retorted that he was “only being honest”.
Barlow said Cocozza had always admitted he “wasn’t good enough”.
“He has been stupid, he has broken the rules, but he has got to live with this for the rest of his life and that’s why I feel bad for him,” the Take That star added.
Fellow judge Tulisa Contostavlos jumped to Barlow’s defence, adding: “I think Gary did all that he could do. At the end of the day he is not a babysitter.
“How many parents do you see with their own children out of control? Gary only met Frankie a few months ago.
“We can’t put this on Gary. Everyone’s their own person and Frankie made his own mistakes.”
Kelly Rowland joked: “He’s got kids of his own.”
Lily is not only tipped as the act to be voted back in but is also one of the favourites to win the show.
Bookmaker Betfair are placing the pink-haired teenager at 6/1 to be crowned this year’s X Factor champion.
