'X Factor's Diva Fever have reportedly fallen out while rehearsing for this week's live show.
According to Metro, Craig Saggers and Joe Al-Smadi got into an argument about who should sing lead vocals this week.
A source said: "Diva Fever have been arguing throughout the day on which lines each of them gets to sing of this week's song. It's not ideal with just 48 hours to go."
