The US singer-songwriter said Hit Me Hard And Soft will be out on 17 May and appeared to suggest new tracks will not be released before the record.

The previous album by Eilish, who collaborates with her brother Finneas O'Connell, was 2021's Happier Than Ever.

She wrote on Instagram: "So crazy to be writing this right now I'm nervy & excited not doing singles I wanna give it to you all at once.

"Finneas and I truly could not be more proud of this album and we absolutely can't wait for you to hear it. Love you, love you, love you."

The announcement was shared alongside an image of Eilish underwater with an open door above her.

Her website says the record should be listened to chronologically so it does what the title says and "hits you hard and soft both lyrically and sonically, while bending genres and defying trends along the way".

Her debut studio album - When We All Fall Asleep, Where Do We Go? - was released in 2019.

The 22-year-old star released the Barbie song What Was I Made For? in 2023, which earned her a second best original song Oscar alongside O'Connell at this year's Academy Awards.

They won their first Oscar in 2022 for No Time To Die, from the James Bond film of the same name.

Eilish, who is known for her advocacy for environmental causes, said she will "limit" the amount of vinyl record variants she releases for the upcoming album to eight.

Her website says the standard black variant is made from 100% recycled materials, while the rest use Eco-Mix or BioVinyl.
