The popstar guest judged at London's O2 today and was given plenty of support from fellow judge Tulisa Contostavlos, who told the crowds that Ora has "years of experience" in the business, even if she has only just reached the top of the charts.
Ora - who wore a white dress and jacket at today's auditions - won huge cheers from the O2 audience, who warmed to her confident and witty approach on the judging panel.
The West London singer flirted with a number of the male acts throughout the day, telling one singer: "I think you're really good looking, so it's a yes from me!" She also teased several other male acts, describing them as "cute" and giving one lucky lad a hug.
An X Factor fan told Digital Spy: "Rita fitted in brilliantly on the panel and was a natural.
"She had great chemistry with Gary and Louis and she was feisty enough to keep up with Tulisa."
The 'RIP' singer became the third guest judge of the series, following stints from Leona Lewis and former Spice Girl Geri Halliwell.
Ora is believed to be in the running to get the X Factor job full-time alongside Halliwell.
