C-Lo is still the queen of beef, even though her bizarre and inane rants have grown increasingly hysterical; her on-off relationship with Twitter has led to many SMH moments over the past couple years. In 2012 she accused former Nirvana skinsman (and current Nirvana Featuring Paul McCartney timekeeper) Dave Grohl of seducing her daughter -- later dismissed by Frances Bean herself, who stated, "Twitter should ban my mother." But that was the height of good taste compared to La Love's reaction (via Twitter, of course) to dead-eyed chanteuse Lana Del Rey's cover of "Heart-Shaped Box." Tweeted @Courtney to LDR: "you do know the song is about my Vagina right? throw down your umbilical noose so i can climb right back umm … so umm next time you sing it, think about my vagina will you?" As I wrote at the time:

FWIW I don't think anyone who's ever heard "Heart-Shaped Box" and knew even an inkling of context had any doubt that it was about Courtney Love's vagina, even though most of us have probably tried to ignore that when we listen it, because it makes a depressing song even more depressing, among other things. Moreover, it's gross that a widow whose husband took his own life is on Twitter bragging that he referred to her vagina as a "noose" in a violently soul-wrenching song. But that's Courtney for ya.

Having said all that, I totally disagree with Frances Bean here! Twitter should never ban Courtney Love. This list (and our timelines) would feel horribly incomplete without her.
