James Arthur, Union J, Rylan Clark and Ella Henderson have all tweeted messages of support of Sones taking third-placed Maloney's spot on the arena tour next year.
Bosses are due to meet today (December 12) to decide Maloney's future on the tour after his alleged behaviour on Sunday's final, The Sun claims.
Maloney is said to have sworn at Carolynne Poole, before reacting angrily to only having one line in the group performance and deciding to travel back home to Liverpool.
Insiders have claimed that they are "90% sure" that Maloney will not be joining the tour, though refunds may need to be supplied to fans who wanted to see him perform, especially as it was revealed he had topped the weekly vote for eight weeks.
A source said: "The other contestants have made no bones about the fact Kye was one of their best friends on the show and they would love him to tour.
"Nobody got on with Chris and after his outburst against Carolynne on Sunday, everyone is furious with him.
"They can't bear the thought of having to tour with Chris while Kye misses out."
Maloney has claimed that he is being bullied, and that he is the victim of a "witch hunt".
Jahmene Douglas and District3 will also form part of the X Factor 2013 tour.
