We first got a taste of Billie Eilish [1] and Rosalía's collab in the trailer for Euphoria's second special episode [2], 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 taking 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 [3]'s "Part 2: Jules" episode, which is set to premiere on Jan. 24. Watch the entrancing video above now.
