Billie Eilish and Rosalía have announced that their much-anticipated collaboration will arrive later this week. The announcement comes with a very brief teaser for the track – titled “Lo Vas A Olvidar” – posted by the pair on social media.

The collab has been on the cards since March 2019, when Rosalía shared a picture from the studio, writing: “can’t wait to finish our song.” Since then, the singer has also discussed working with Eilish remotely during lockdown. “You guys have been waiting for this,” Eilish writes on Instagram, which tbh feels like a bit of an understatement.

“Lo Vas A Olvidar” is now set to arrive on Thursday (January 21), and will debut alongside the official video. The track is also set to feature in the second special episode of Euphoria, premiering on HBO January 24 (watch a recent trailer here).

Recently, Billie Eilish also announced a forthcoming photo book spanning her life and career. Her most recent single, “Therefore I Am”, was released in November last year.
