"He was real nervous. He was like, 'S---. Should I be putting this out into the world?' Because he's like, 'People know me for this thing and it's like I've never been this raw,'" Blanco said of JB's song. "He's raw on this song. This song brought us so much closer together. And it was just he's really opening up on this and he's super vulnerable.
"We were just talking about we all play this Superman every day," he continued. "I'm sure you do for your family, for your friends, and everyone's counting on you for so many things. You do a lot of stuff for a lot of people and sometimes you get f---ed up. I know for sure it doesn't matter. You do. I do. We all do. And why do you have to be this superhero? Why can't you be like one of your kids for a second and be like, 'I don't want to do. I just want to cry. I just want to be sad.' There's this weird stigma and this thing where men are supposed to be this. And it's like, 'No, I want to be vulnerable. I want to cry. I want to have a good cry.'"
Blanco previously worked with Bieber for 2015 hit "Love Yourself" off Bieber's album Purpose. Both were Grammy-nominated. "Lonely" follows Bieber's previously released single "Holy" featuring Chance the Rapper.
