I found this on Twitter:

I have officially lost all respect for Lorde if this is true.... The fact that she is making fun of one of the biggest and most talented artists in the world is really saying something about her character. Why would she do that? Adele is making millions of dollars off of two albums, a live DVD/CD, and a digital single. Lorde has a #1 single, but she still has a long way to go to catch up to Adele.
