Eilish previously spoke about the encounter in an interview with ET Online, where she revealed that Bieber shared a screenshot of one of her old messages to him, which she began sending as a "super fan" back in 2014. She said she was pretty embarrassed by the encounter but was also excited to speak with him.

ET's Katie Krause talked to Eilish at Spotify's 'The Billie Eilish Experience' in Los Angeles. The event is in support of her new album, 'When We All Fall Asleep, Where Do We Go?,' out now. The singer's Los Angeles pop-up runs from March 29 through March 31.

“The first thing he sent was a screenshot of a DM I sent him in 2014…you know how when you follow somebody, you can see everything they DM’d you in the past? It, like, it felt good and it felt bad at the same time,” Eilish said.

While she wouldn't express exactly what went down in the conversation, she did promise that fans would find out soon.

"One day you'll find out," she said. "But that s**t was crazy."
