Celine Dion Stops Billboard Music Awards Interview to Sing Along to Cher’s ‘Believe’ (Videos)

Not even Dion could stop herself from singing along to Cher’s iconic song on Sunday night

Celine Dion had to stop her backstage interview at the 2017 Billboard Music Awards to sing along to Cher‘s performance of “Believe.”

As the 71-year-old took the stage on Sunday night, Dion paused to watch the fellow performer on the monitor and started an impromptu karaoke session with reporters backstage.

Cher accepted the Icon award at the Billboard Music Awards. During her acceptance speech, she said, “I want to thank my mom. When I was really young my mom said, ‘You’re not going to be the smartest, you’re not going to be the prettiest. You’re not going to be the most talented. But you’re going to be special. And then when I met Sonny [Bono], he said the same thing. And there was really nothing about me that lead anyone [else] to believe that I was going to be special.”

Dion also performed on Sunday night, singing “My Heart Will Go On” to celebrate the 20th anniversary of “Titanic.” The singer, donning a beautiful white gown, sang the theme song while video clips of Leonardo DiCaprio and Kate Winslet from the movie played on a screen behind her.

Dion received a standing ovation — the song, one of the most iconic theme songs from a movie, won an Academy Award for Best Original Song in 1998.
