In terms of music, we've been getting blessed in 2021. And this new week shows no signs of that letting up! Earlier today, Billie Eilish and Rosalia teased their new collab song 'Lo Vas A Olvidar' in the support of HBO's Euphoria. Two different yet incredibly talented voices on the same track and possibly in Spanish is going to make this song a huge record. Check out both their teaser posts via Instagram below! 'Lo Vas A Olvidar' is out this Friday!
