Pop star Lorde has announced that she's working on her third album.

The 22-year-old singer took to social media to thank fans for their response to her last album, Melodrama, and announced that the "Third one is in the oven."

In a rare post on Instagram, Lorde said: "Apparently Melodrama came out two years ago today.. Want to say thankyou for how you took that record and made it your own. Swells my damn heart thinking about your love for it and your willingness to go there with me and to dance the way we did together. The day it came out i did a jigsaw puzzle all day in my hotel room in NY. I felt so emptied, i didn't really know yet that you make a record and get filled up, and then releasing it empties you.. and slowly fills you up again. I was such a baby making that work, lots of emotions and learning so much all the time. Feels like i've grown a lot since then, i've been to antartica, i have a dog now and a cat and i can bake bread and cook dinner and keep plants alive etc. It's a good life you've given me. Thankyou thankyou. Third one in the oven. L xx xxx x x xx x x
