Fleur, who is being mentored by Simon Cowell, was snapped arriving at Wembley Arena and looked sophisticated in a navy trouser suit teamed with a white cropped top.
The star piled her hair into an updo, topped off her outfit with dainty heeled sandals and was all smiles as she strutted her stuff on the red carpet.
During the event, which celebrates music of black origin, Fleur sat alongside some of her fellow X Factor singers and together they posed for selfies.
In one shot, the 28-year-old contestant is looking fierce while sitting next to Andrea Faustini - who is in Mel B's boys' category. Posting the snap on Twitter, she simply said: "MOBO2014."
Meanwhile, Fleur had previously posed for a selfie with Jake Quickenden - also in Mel's group - which was taken as they made their way to the prestigious music event.
Sharing it on his Twitter page, Jake told followers: "Me and @FleurEast on the way to the @MOBOAwards."
The MOBOs were hosted by Mel B and Xtra Factor presenter Sarah-Jane Crawford, so it was only right the X Factor gang were there to cheer them on!
After their night on the tiles, Andrea tweeted this morning: "Loved yesterday's #MOBOAwards2014 with @OfficialMelB and my friends @PaulAkister @JakeQuickenden @jwaltonmusic and @FleurEast."
With the theme being 'Movie Night' this Saturday, no doubt Fleur, Andrea, Paul, Jake and Jack were up bright and early and back to rehearsals so they are ready to take the stage by storm!
