It also saw her reunited with her 'X Factor' rival Tulisa, and they both sashayed their way down the red carpet, reigniting their style war.
Nicole flashed the flesh in a low-cut, high-split LBD teamed with a chunky vintage Chanel gold pendant from the Susan Caplan Vintage Collection.
Meanwhile, Tulisa went for a full length white gown which showed off her cleavage, and it has to be said it was a much better look than her pink feathered monstrosity from last year's event.
Both ladies were out to see if 'The X Factor' had bagged the title of Best Talent Show, where it was up against 'Strictly Come Dancing', 'Dancing On Ice', 'The Voice' and 'Britain's Got Talent'.
Rumours are currently rife Tulisa is facing the axe from the show, with other reports claiming she is miffed with show's bosses who have are said to have already signed up Nicole for this year's series, but not her.
