We first got a taste of Billie Eilish and Rosalía's collab in the trailer for Euphoria's second special episode, and now it has finally arrived. On Jan. 21, the singers dropped their highly anticipated single, "Lo Vas a Olvidar," complete with a music video. In the visual, the two take turns singing the melancholic lyrics of the track against a dark background, and Eilish even belts out some of the verses in Spanish. Both the song and the video are equally dreamy. The collab will be featured on Euphoria's "Part 2: Jules" episode, which is set to premiere on Jan. 24. Watch the entrancing video above now.
