What would Billie Eilish tell her 10-year-old self? That she could call Justin Bieber 'any time' and 'he'll answer'

The Grammy winner is a well-documented Belieber.

Belieber Billie Eilish has an important message for her younger self.

Eilish joined Alex Wolff for Vogue's latest "Off the Cuff" segment published Friday, where the pals spoke about their close friendship and grilled each other with questions. One such query from Wolff was: "If you could send your 10-year-old self one message from the future, what would that be?"

For the noted Justin Bieber superfan, the response came easily. "I would say, 'You can and have and do call Justin Bieber at any given time," Eilish replied. "Any time you want, you can. And he'll answer."

Eilish first opened up about her love for the Canadian pop star in a 2019 Carpool Karaoke segment on James Corden's late night show, where she recounted meeting Bieber for the first time at Coachella during Ariana Grande's set and freaking out.

"All Coachella weekend, I was like, 'Don't surprise me with Justin Bieber,' she recalled to Corden. "I can't take it. I can't have to do this show and Justin Bieber's going to be there." Of recognizing Bieber immediately while she was watching Grande perform, Eilish said, "I know his body language, I know how he stands, I know where he wears his pants." 

In 2019, Eilish recruited her pop idol for a remix of her hit song "Bad Guy." The following year, Bieber made headlines for his emotional interview with Apple's Zane Lowe in promotion of his album Changes, where he tearfully spoke about his friendship with Eilish and his desire to protect her as a young artist in the industry.

“I definitely feel protective of her," Bieber said. "It was hard for me being that young and being in the industry and not knowing where to turn. Everyone telling me they love me, and, you know, just turn their back on you in a second. If she ever needs me, I’m gonna be here for her. I don’t want her to go through anything I went through. I don’t wish that upon anybody. If she ever needs me, I’m just a call away.”
