Her real name, Ella Marija Lani Yelich-O'Connor, is a lot longer and more traditional.
"It was actually a really quick decision. It's quite funny, because I'm like, wow, if I'd known I would be having that name for the rest of my life I probably would have spent more than two days on it," she said in an interview with 60 Minutes.
"It was a good spontaneous choice, I think. I'm quite proud of my 16-year-old self for not messing that one up because if I'd given myself a cool, weird, hip name that I hated now that would be super annoying."
She added, "It was that nobility, aristocracy obsession that I had. I hit upon 'Lord' and loved the way it sounded, and then I was like, it would be quite cool to add an E to feminise it."
She even went on to discuss her feminist views.
"It's totally not about me, it's about all women — women who might not have the opportunities that I have or the privileges that I have, trying to fight for better conditions and better treatment of all women, whether that be trans women or women of colour or women in professions that don't typically get a lot of respect.
"That, to me, is what feminism is about, because I think, like, no one needs to fight for me to have an okay run. I'm gonna be fine, but there are women in other, different situations to me that...don't have a voice or that have a voice and don't have anybody listening to it."
