Billie Eilish and Rosalía have announced a new collaborative track, to be released tomorrow (January 21st) at 5pm GMT. The track, called 'Lo Vas a Olvidar', is for the HBO show Euphoria. It will be produced by Eilish's brother Finneas.

Rosalía has been teasing the collaboration for months now, telling Zane Lowe in April: “I think it’s getting quite close… I finished the arrangements. I feel like the production, the sound design is almost done, so I just need Billie to send the vocals and they send me the ideas that they want to add because we are there.”

Eilish released a single called 'Therefore I Am' in 2020, and is gearing up for the premiere of her Apple TV+ documentary Billie Eilish: The World's A Little Blurry as well as the release of a self-titled photo book.

Rosalía's sophomore album EL MAL QUERER was released to critical acclaim in 2018.
