What makes the Billboard Music Awards, airing Sunday evening on ABC, different from other awards shows?

It's all about the fans, said one of the show's hosts, Ludacris.

"Because it's the people that vote," Ludacris told ABC News. "When it comes to the charts, every artist is constantly looking at the Billboard charts, but this award show has been about the people, for the people, by the people for decades."

The rapper's co-host Ciara agreed, adding that the BBMAs hold a special place in her heart.

"I remember my first song, 'Goodies,' being number one for eight weeks on the 'Billboard' chart and it was pretty huge," she recalled.

The Weeknd is the leading nominee for this year's Billboard Music Awards. The R&B singer earned nominations in 16 categories, including Top Artist and Top Male Artist.

Fellow Canadian Justin Bieber received nods in 11 categories, while rappers Fetty Wap and Drake will both compete in 10 categories. Pop stars Adele and Taylor Swift each have eight nominations.

This year’s show, broadcast live at the T-Mobile Arena in Las Vegas, will feature live performances from artists including Bieber, DNCE, Ariana Grande, Demi Lovato, Pink, Rihanna, Britney Spears, Meghan Trainor, and Lukas Graham, and collaborations with Fifth Harmony featuring Ty Dolla $ign, Nick Jonas with Tove Lo, and Blake Shelton and Gwen Stefani. Madonna will also perform a Prince tribute.

The list of high-profile presenters includes new "Bachelorette" star Jojo Fletcher, Laverne Cox, Heidi Klum, Kelly Rowland, Tyrese, and Zendaya.
