Nicole Scherzinger has been fulfilling her X-Factor judging duties in high style.  After rocking two Victoria Beckham dresses flawlessly, the Pussycat Doll showed up in a red and fuchsia pencil dress, which totally flaunted her fab figure.  Paired with pink lips, a red manicure/pedicure and bright red platforms, Nicole scored our Best look of the day.  The Situation has been busy jetsetting around the world, promoting his hit MTV television show in his infamous Jersey Shore style, so maybe he was a little fatigued when he accidentally sported different colored Reebok kicks on his feet?
