Chloe and Halle Bailey – known professionally as Chloe x Halle – aren’t your typical sisters.

For one thing, the Atlanta teens just returned home from the European leg of Beyoncé‘s Formation World Tour and have been dubbed “angelic aliens” by the singer. But they also say that despite spending all their time together and living in close quarters on the road, they never really argue.

“You know, my sister and I, we never fight. It will be like one second and then we’ll be like, ‘I’m sorry, no I’m sorry,'” Chloe, 18, told PEOPLE Now’s Jeremy Parsons and Andrea Boehlke during their Facebook Live chat. “We’re best friends.”

“It’s always over the smallest things like, ‘You’re wearing my shoes, you have my coconut oil,'” adds Halle, 16.

In fact, the sisters say they love performing together. “Music is so personal,” says Halle. “I’m so happy I have my sister to do it with.”

Adds Chloe: “We can be honest, we can be like, ‘I like that, I don’t like that!”

Chloe and Halle’s career exploded after Beyoncé shared their 2008 cover of her song “Pretty Hurts” on her Facebook page.

Over 12 million views later, Beyoncé’s protégés have become music’s next big thing. Their signature harmonies and songwriting prowess got them signed with Queen Bey’s Parkwood Entertainment management firm, secured them a performance spot on the 2016 BET Awards, and even helped them nab a cameo on the singer’s latest visual album, Lemonade.
