Demi Moore's Secret to Beauty!

Demi Moore told David Letterman last night that she's a fan of leech therapy. The 46-year-old admitted to visiting Austria to partake in a detox treatment that involves your body being covered in leeches. Demi said, "I was in Austria doing a cleanse and part of the treatment was leech therapy. These aren't just swamp leeches though - we are talking about highly trained medical leeches. These are not some low level scavengers - we're talking high level blood suckers."  Woooaaaah??!!!!
