Lorde has been learning piano for her next album.

The Royals hitmaker released her second record Melodrama, which featured producer Jack Antonoff playing keys in 2017, but the singer has been practicing ahead of her third studio LP.

Opening up to fans in a newsletter this week, Lorde wrote: "I haven't started properly on the next record yet, and I'm not sure how long it'll be...

"But I've been teaching myself how to play piano, and here and there little bits come out.

"I think this next one will probably be born around the piano in my house, me and my friends, keeping it simple...

"But know that for now I'm happy here at home, living quietly and simply, eating toast, going for walks, swimming. And you'll hear all about it soon enough."

Meanwhile, the 22-year-old star also took the opportunity to praise the crowds she performed to on her recent world tour.

Lorde admitted it had been an amazing experience, while thanking her fans for "continuing to change my life, year after year; for living inside the work that I make; for always being ready for what's round the corner".

She added: "I've never felt richer than in those moments with you, all of us heaving to 'Green Light', or singing 'Writer [in the Dark'] together, or 'Supercut'.

"The way you took this record and made it yours will be a highlight of my life forever."
