Billie Eilish has revealed that a new collaboration with Spanish singer-songwriter Rosalía might be available soon.

Speaking with BBC 1's Annie Mac, she admitted that she has been in the studio with the Spanish singer and gave details on their time together, " In that session I sang some notes I have never even thought about! She knows what she wants, it’s very refreshing… I was like, ‘wow, you’re the only person I’ve met who’s really like this. It was dope to work with her. [She’s] the nicest girl, oh my god."

Earlier in the year, she announced details of her upcoming debut album When We Fall Asleep, Where Do We Go? together with a new single, 'bury a friend'. The album will also feature previously released singles 'you should see me in a crown' and 'when the party's over'.

When We Fall Asleep, Where Do We Go? will be released on March 29.
