How did Courtney Love feel when Lana Del Rey recently covered Nirvana's "Heart-Shaped Box"? Well ... "Has anyone told Lana what Heartshaped box is about?" Love tweeted indignantly today, before educating Del Rey herself: "@LanaDelRey you do know the song is about my Vagina right? throw down your umbilical noose so i can climb right back ... so umm next time you sing it, think about my vagina will you?" Next time, we're pretty sure that everyone will think about that, Courtney.
