The X Factor 2012: Nicole Scherzinger vs Tulisa
The pair have been whipping out their tightest, hottest dresses to impress the crowds at the show's auditions.
When the judges hit Cardiff, Tulisa, 23, chose a striped blue body-con number, while 34-year-old Nicole opted for a yellow mini-dress.
But Tulisa - who was recently votest sexiest woman in the world (while Nicole came in at 43) - toned down her look for the recent round of auditions in Newcastle.
She chose a rather sophisticated knee-length pastel number, while Nicole continued her sexy style with a tiny sea-green dress.
It's an X Factor style war! But who wins - sassy US singer Scherzy, or home-grown tough girl Tulisa?
