According to Love the haunting happened in the late 90s when Love was in love with the actor Edward Norton and they were about to move into a new pad together.
"When I moved to Hancock Park from Seattle with Frances [Bean, her and Cobain's daughter] and Edward, I saw Kurt in a chair for a moment," she revealed.
From Love's account the poltergeist wasn't particularly petrifying. Instead, Cobain's spirit was totally chill with nary a spooky 'wooooo' or frightful 'boo!' to be had.
Instead, Love recounted that, "He said 'Hi' to me and then he left".
Not exactly a story to keep you up at night and sleeping with the lights on, but it is one that's completely in line with the grunge attitude. Oh well, whatever, never mind.
