It's the penultimate live show tomorrow night and former Cleopatra star Cleo is demanding everything for her performance.
But Cleo's demands, from smoke machines to troupes of backing dancers, haven't made her any friends backstage.
And even her coach Will.i.am is getting annoyed.
“Cleo is absolutely going for it this week. She has made no bones about the fact she wants her solo performance to blow the others out of the water," a source told The Sun newspaper today. “She is determined that the song choice has to be perfect and has also asked the bosses to pull out all the stops when it comes to the special effects.
“She knows what she wants and certainly isn’t afraid to ask for it. For her costume, only a catsuit will do.
“The team are doing their best to accommodate her, but the growing list of demands isn’t doing her any favours."
The source added: “The rest of the contestants are all getting wound up because they don’t see how she is managing to get away with bossing everyone about.”
An insider also told the Daily Mirror that Will is “sick to death of dealing with [Cleo]” after less than two weeks working on the live finals.
Last week saw Cleo singing Imagine by John Lennon to win the public vote ahead of Leanne Jarvis.
This week she'll be going head to head with favourite Leah McFall, as the audience are given total control over who will make it through to the last live show final.
The show airs tomorrow night on BBC One.
