Dannii Minogue has reportedly not spoken to 'X Factor' boss Simon Cowell since Sunday's show.
The results programme saw Cowell choose to save twins John & Edward, leaving the judging panel in deadlock.
Minogue's act Lucie Jones was then eliminated from the contest by the earlier public vote.
A friend told The Sun: "Dannii has declared war on Simon. She is so angry with him and hasn't spoken to him since the show.
"Backstage on Sunday night it was very frosty and Simon just made things worse by smirking all the time."
Other friends of Minogue alleged that Cowell hoped to keep John & Edward in the show to aid his own three acts who remain in the competition.
