These are not the best lovey-dovey partnerships in visual art history. That would be lame.
Instead, kudos were earned for partnerships wrought with infidelities and general messed-up-ness. Because how else does one make art if not from a place of titanic heartbreak and crushing depression?
(Kidding. Kind of.)
