Joan Rivers claims she never breaks a sweat thanks to vodka. “I always spray my costumes with vodka and water. It’s an old Broadway trick — two-thirds water and one-third vodka, spray your armpits and you’ll never smell again,” she told attendees at the Night of a Billion Reality stars event in LA. Rivers also told the crowd she occasionally uses the mixture to wash her clothes. The E! fashion commentator is starring in a Funnyordie.com video short produced with Svedka, where she appears as a wise-cracking head in a jar being stalked by paparazzi.
