For those that don't know, Melodrama features a track called The Louvre, in which Lorde sings: "We're the greatest / They'll hang us in the Louvre / Down the back, but who cares? / Still the Louvre".
In an interview with radio station Triple J, Richard said her friends told her she was "crazy as f***" but "the record is so special and very beautiful" she did it anyway.
"I really like Lorde, she's the one I love the most," she said.
When Sam McKinniss - who painted the lithograph- shared Richard's photo on Instagram, Richard commented: "I'm very glad cause we owe you this legendary beautiful art cover. I am very proud of this record, like a proud mum...and it was very importantt to me to do it. It was a lifetime mission."
