No sign of the RIP singer on the red carpet...

As the judges walked the glitzy red carpet on Wednesday night there was one notable absence.

No bleach blonde hair, no daring outfits and certainly no twangy west London accent.

Rita Ora was nowhere to be seen alongside her fellow judges Cheryl, Nick Grimshaw and Simon.

We bet Mr Nasty wasn’t too please about that…

The official line is that Reets was off on stateside promotional duties organised before she had signed up for the X Factor.

But a sneaky source told Now: ‘Her gig in LA was actually only organised a few days before it took place and Rita was expected to come back for the launch. Her decision came as a shock to show bosses.’

This isn’t the first time Rita has been forced to miss a commitment with the ITV primetime talent show.

Last month, she was forced to pull out of auditions in order to attend a fashion show to promote her new underwear range for Tezenis.

The last-minute filming had been scheduled to make up for lost time after the tragic passing of Simon’s mother but Rita was unable to attend.

A show spokesman said: ‘This is one of the new audition dates which we’ve added after having to cancel dates in Manchester and the first London date. Rita could not make today work because of prior commitments which she couldn’t move, so we are doing today’s auditions with the other three judges.’

Back at Wembley Arena, fellow judge and friend Nick Grimshaw mocked Rita’s no-show.

On Instagram, he said: ‘We are having such a miserable day missing Rita Ora,’ alongside a photo of himself, Cheryl Cole and Simon Cowell laughing and having fun.

Rita also missed a day of Manchester auditions to attend a fashion show in Paris.

Last year Mel B was forced to miss out on the first part of the X Factor final due to a ‘mystery illness’.

Let’s hope Rita’s repeat absences aren’t a sign of things to come…
