TV show Dancing With The Stars has turned Penn Jillette from a heavyweight magician into a slimline shadow of his former self. The star - one half of magician double act Penn and Teller - has shed a staggering 23 kilograms training for his appearance on the reality show, and he reveals how it has changed his life. Jillette, 52, says, "I've lost 50 pounds. I started running eight miles a day and began to eat more healthy before the show started. Now I rehearse five hours a day."
