Billie Eilish teases collaboration with Rosalía

Billie Eilish's debut album When We All Fall Asleep, Where Do We Go? is just around the corner. The "bury a friend" singer has been coy with the details on just what to expect from the record, but in an interview with Annie Mac earlier today, she revealed that she recently hit the studio to record with Catalan powerhouse Rosalía.

While Eilish didn't elaborate too much on what the collaboration will entail or whether it will appear on her forthcoming album, she did confirm that Rosalía pushed her vocals to new heights during the session. "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,'" Eilish said of the El Mal Querer artist. "[She's] the nicest girl, oh my god."
