Last week, pop singer Lana Del Ray performed a cover of Nirvana's Heart Shaped Box in Australia and did a really good job of it.  Her performance must have really upset Kurt Cobain's widow Courtney Love as she tweeted to Lana the real meaning of the song. 

The tweets have since been deleted but we have the screenshots before they were taken down.  You can see that Courtney gave Lana a rock history lesson.

There you have it... apparently the song is about Courtney's vagina and not about someone who feels they are trapped in a box trying to get out.

Then Courtney decided to apologize.

To which Lana responded.
