Billie Eilish has shared pictures of herself as a young Justin Bieber fan after the singer talked about his need to “protect” her.

Eilish, 18, posted a snap of herself as a younger teenager with a Bieber vest on, as well as images of her bedroom adorned with posters of the Canadian pop star and the sign on her bedroom door that read: “Forever Belieber, Billie’s room.”

The US singer-songwriter, who has just released the new James Bond theme No Time To Die, made the post after Bieber, 25, broke down in tears in an interview with Zane Lowe.

Reflecting on his troubles having risen to fame at a young age, and Eilish’s sudden debut into the spotlight over the past year, he said: “Let her do her thing and if she ever needs me, I’m going to be here for her, but yeah, just protecting those moments because people take for granted encounters.

“I just want to protect her, you know? I don’t want her to lose it, I don’t want her to go through anything I went through.

“I don’t wish that upon anybody. So, if she ever needs me, I’m just a call away.”

Touched by the interview, Eilish shared a clip of Bieber’s chat along with her throwback pictures.
