Queen of the Cougars, Demi Moore, 46, will seemingly do anything to keep up with 30-year-old hubby Ashton Kutcher.  Moore's a huge fan of a detox treatment called leech therapy.  Yes. You read right. Leech therapy!  Demi visited a spa in Austria that offers it as part of their services. The 'highly trained medical leeches' attach themselves to you and detoxify your blood.  According to Moore, it is so effective that she's going back for more!  Demi fancies herself a 'health' trailblazer. "I feel like I've always been someone looking for the cutting edge of things that optimize your health and healing," she says.

She explained it in detail last night on Letterman!  She must be doing something right cuz she looks freakin HOT but I dont think I will be trying this anytime soon.  Nasty!!!!
