In what is probably the grossest advertisement in history, 50 year old Madonna is using her crotch to sell Louis Vuitton bags. The appeal isn't readily apparent, unless LV is going for a huge "WTF?!?" Though both Madonna's funbags and LV's handbags are made of leather, so the move makes some sense.
Remember when Sheena did that on America's Next Top Model?
Madonna, you're such a biter. Sheena was adorable. You, not so much.
