Billboard Music Awards: Mariah Carey Wows Audience with Vocal Acrobatics (Video)

Idina Menzel introduced the pop/R&B vocalist.

Mariah Carey returned to the Billboard Music Awards stage for the first time in 17 years (wearing a low-cut sparkling gown and David Yurman jewels) to perform "Vision of Love" and "Infinity" on Sunday night.

Carey took audiences back in time, belting out her first single, "Vision of Love," before performing her new hit track "Infinity." She enchanted the audience with her impressive vocal range as she performed against a heavenly white backdrop, from the color of the piano to the outfits of her backup performers.

"Infinity" has entered the Hot 100 chart as the first single from Carey's forthcoming compilation album. In the past, the Billboard Awards has recognized Carey for both song of the decade and artist of the decade.

The Billboard Music Awards were co-hosted by Ludacris and Chrissy Teigen and featured performances by artists including Wiz Khalifa, Fall Out Boy, Kanye West and Ed Sheeran.
