Nicole Scherzinger is still guest judge on the X Factor.

She’s covering the boot camp stage for Dannii Mingoue who’s on maternity leave and Cheryl Cole who’s battling to get better after being struck down with malaria.

The Pussycat Doll singer has finally given up her obsession with wearing pre-selected Victoria Beckham dresses and this time opted for a colourful Tibi Pre-Fall 2010.

Yesterday was gloriously sunny day in London. I would’ve loved her to have worn one of the amazing Tibi Spring 2010 looks, but thanks to the vibrant yellow print on her dress it doesn’t quite feel like a Fall dress.

The singer wore YSL Y bow slingbacks which complemented her black bow belt.
