Chloe and Halle are beaming. They certainly have plenty of reasons to smile. A couple of years after channeling summertime boredom into an impressive YouTube career with millions of views, the teenaged sisters posted a cover of Beyoncé’s “Pretty Hurts.” To their surprise, their heart-wrenching rendition not only reached the superstar herself, but also landed them a deal with her production company. In the four years since, Chloe x Halle’s lush harmonies have earned them an opening slot on Bey’s Formation world tour and an appearance in Bey’s critically acclaimed visual album Lemonade as well as a feature on Michelle Obama’s charity single “This Is For My Girls.” Now, Chloe, 19, and Halle, 17, are gearing up to release their long-awaited debut album.

Still, they’ve seen plenty of challenges, from hearing the word “no” more times than they can count to experiencing the pitfalls of being young girls in a testosterone-driven industry. But their bright, be-happy dispositions and “sisters-against-the-world” mentalities have helped them conquer it all. The two spots of sunshine sat down with Complex to talk constructive criticism, sisterly spats, and of course, Queen Bey. This interview was performed in partnership with Peet’s Coffee, who is celebrating the passion that drives people like Chloe x Halle in the pursuit of their craft.
