`Shopaholic Showdown' (titled `Ultimate Shopper' in its first season) pits four slaves-to-fashion against one another in a series of challenges that test their chic creativity and quick-thinking fashion sense. In each episode the four contestants are let loose to roam a specially built fashion store to complete the challenges, after which they come under the exacting gaze of a discerning panel: Singer Holly Valance and fashion expert Brix Smith-Start return as judges, joined by newcomer Jason Gardiner, the sharp-tongued evaluator from `Dancing on Ice'. As well, guest judges each week include Kelly Brook, Abbey Clancy, Grace Woodward, Lisa Snowdon, Caprice, Lydia Bright and Jonathan Phang. The contestant who is declared the winner at the end of each episode gets to take home all of her chosen pieces.
