Jessica Biel has been voted the "cleanest" female celebrity. Not in the hygiene sense of the word (although, looking at some of the names gracing the "dirty list"…). 'The Illusionist' actress and girlfriend of Justin Timberlake was named the most healthy-living star by SoCal Cleanse Detox users, while (quelle surprise) Amy Winehouse was voted the "dirtiest" and most unhealthy. On the upside, the singer has won a 12-month supply of SoCal Cleanse Detox Formula - a detox supplement - and a Detox Lifestyle Makeover with Detox and Fitness Expert Cynthia Lea.
