Johnny Depp & Vanessa Paradis

Allegedly it was this couple's hatred of hygiene that kept them together for so long. An "insider" revealed that "Johhny isn't big on personal cleanliness,” adding that he “usually smells because he rarely showers.” And Vanessa wears “no makeup and [has] unruly hair—she’s a bit of a mess normally,” the source says. “They found their perfect match in each other—it’s hard to be around them. Their personal hygiene is not their priority.” Maybe they split because one of them suddenly got into grooming. [Newser]
