A risqué video of pop princess Rita Ora (24) has reportedly been leaked online.
The show's new female judge is said to be worried after a risqué video, filmed some months ago, was uploaded online this week.
In the grainy footage, the singer is reportedly seen cavorting in a car, twerking and repeatedly grabbing her bottom.
A source close to Ora said that the artist is determined to maintain her family-friendly X Factor image.
It appears that the 13-second clip was filmed using a mobile phone.
In the clip, Ora dances to Mark Ronson's No 1 tune 'Uptown Funk', which was released in 2014.
