Demi Moore was on The Late Show with David Letterman last night to promote her new movie 'Flawless' and talked about her recent trip to Australia and doing leech therapy as part of a cleansing process. She says the leeches actually release an enzyme that detoxifies your blood and they put the first one in her belly button... Ewwww! If you wanna get straight to the leech talk you can forward to about the 3:30 mark. It's crazy and definitely worth hearing her talk about!
