WE'VE finally reached the all-important X Factor live stages – but the head judge was conspicuously missing from Saturday's show.
So where was Simon Cowell, what stopped him from attending and will he be back tonight? Here's the full lowdown.
ITV Simon is appearing on The X Factor on Sunday instead due to his hospital trip on Friday
Why wasn't Simon Cowell on The X Factor on Saturday night?
After Simon's admission to hospital on Friday following an accident in his London home, he was missing from the Saturday show – with plans to appear on Sunday instead.
Louis Walsh and Sharon Osbourne's categories, the boys and girls, featured on Saturday 28 October, having originally been planned for Sunday.
Simon and Nicole's groups and overs will be the last to perform this weekend.
Will Simon be back on The X Factor tonight?
The judge in chief's return to the show for tonight's episode is looking doubtful after his fall.
There had been hope Simon, 58, would be well enough to return to the ITV show tonight, but an insider has now claimed it doesn't look likely.
The source told the Mirror Online: "The decision is not 100 per cent yet but it's very likely he'll sit out this one on doctor's advice."
"Alesha Dixon is ready to step in as a substitute judge if necessary."
Simon's category, the groups, are set to go head to head with Nicole's Overs tonight after the running order was switched around to accommodate Simon's absence last night.
Saturday's live show saw Spencer Sutherland become the first person to leave the competition.
What happened in the accident at Simon Cowell's home?
The Sun's Bizarre column exclusively revealed how Simon Cowell was stretchered away and rushed to hospital in a neck brace after an accident at his London home.
The 58-year-old is believed to have fainted and fallen down the stairs after fetching a cup of hot milk.
He had been at a Little Mix concert and had woken up at 6.45am, before an ambulance was called at 8am on Friday.
Simon gave photographers the thumbs up as he was pictured returning home after his fall.
A source close to him said: "It’s been a scary morning. It was very early and Simon was going down his stairs to get some hot milk because he couldn’t sleep.
"He fainted and is thought to have fallen down the stairs.
"An ambulance was called and he was stretchered out of the house in a neck brace surrounded by worried aides."

When have X Factor presenters missed shows in the past?
It's not unheard of for X Factor judges to miss shows, with stand-ins often drafted in to make up the panel.
During the auditions this year, both Nicole Scherzinger and Sharon Osbourne were absent at various points.
Sharon was forced to pull out of the Edinburgh auditions due to a back problem, while a diary clash meant Nicole sat out the Manchester leg.
On both occasions, erstwhile Britain's Got Talent judge Alesha Dixon was on hand to fill in.
It's not the first time Simon has been missing during this series, either.
He was mysteriously missing for the first half of one of the auditions shows, with Louis Walsh telling cameras his boss was "running late".
The trio struggled on in Simon's absence, with Louis briefly assuming the mantle of head judge, before the impatient looking mogul finally arrived after reportedly getting stuck in traffic.
