New X Factor judge Tulisa Contostavlos is apparently "on edge," and it's not because of reports that Gary Barlow has lost track of Frankie. Rather, according to insiders, bosses want to bring Cheryl Cole back (yes, that rumour again) to boost ratings.
With the show having lost around 2 million fans since last year, crisis talks are happening between producers behind the scenes.
A source revealed: "Simon has let he judging panel in no doubt he's not happy about the ratings drop."
"There has been a lot of talk about Cheryl being brought boost ratings," the source continued. "Tulisa in particular is increasingly on edge. Everyone knows Simon is not afraid to make changes if things aren't working and that worries them."
The source added: "He's even considering going back on to the show himself as a guest judge."
But it seems that Simon has other plans, with a source also telling Closer that he wanted Tulisa to turn into Cheryl instead of bringing the Geordie back to replace her!
