Billie Eilish joined “The Late Late Show” host James Corden for “Carpool Karaoke,” and the long-awaited segment did not disappoint.

The two began the ride with Eilish’s upbeat “bad guy” before Eilish launched into the story of how she met her idol Justin Bieber for the first time. The two even sang a bit of Bieber’s hit song “Baby.”

She recalls how she recognized him instantly while watching Ariana Grande perform. As a long-time fan, she was in complete shock saying, “he just stood, like, five feet away from me, perfectly still.”

After singing “all the good girls go to hell,” Corden gave Eilish a ukulele to play. She performed a bit of “I Will” by the Beatles and also played her own song “8.” Then Corden began playing Eilish’s first hit “Ocean Eyes,” and the singer-songwriter got quite emotional.

“This song gave me my life,” Eilish said. “I was 13 when I recorded this song. That song is the reason why I have the life I have”

The two then stopped by Eilish’s childhood home, where she actually still lives, and talked about creating her debut album. She recalls how her and her brother Finneas made “WHEN WE ALL FALL ASLEEP, WHERE DO WE GO?” right in his tiny bedroom. Eilish’s mom came in at one point and got emotional talking about her two kids’ success.

“It’s never not been mind-blowing,” Eilish’s mom said. “The whole experience is so crazy”

Eilish and Corden ended the segment back in the car with a touching rendition of Eilish “when the party’s over.”

Eilish’s Crazy Year

Eilish’s debut album has skyrocketed the young singer to fame this past year. “WHEN WE ALL FALL ASLEEP, WHERE DO WE GO?” was the most-streamed album on Spotify in 2019. It was also nominated for Album of the Year.

Her hit song “bad guy” was nominated for two more Grammy Awards- Song of the Year and Record of the Year. It reached No. 1 on the Billboard Hot 100 list this summer and was one of the top three most-streamed songs on Spotify.

Eilish was also recently honored at the Billboard Women in Music event with the Women of the Year award. At 17, she was the youngest artist to ever receive the award.

The singer celebrated her milestone 18th birthday just yesterday, so I’m sure there will be many more years of music and success in her future.
