Dick Clark productions and NBC announced today that the rumors are true – Christina Aguilera and Demi Lovato have teamed up for the first time and will perform the world television debut of Aguilera’s new single, Fall In Line, featuring Lovato, at the “2018 Billboard Music Awards.” Rumors have been swirling that the pop chanteuses have been collaborating together on a track since early this year, and fans have been eagerly awaiting confirmation of the news.

Aguilera and Lovato will join previously announced performers BTS, Camila Cabello, Kelly Clarkson, Ariana Grande, John Legend, Dua Lipa and Shawn Mendes, on a night filled with music’s biggest names. It was also announced that global superstar, Janet Jackson, will receive this year’s ICON Award, given to artists who have led industry-defining careers and shaped the music landscape. Jackson will also take the stage for a highly anticipated performance of her greatest hits, marking her first performance on television in nine years.

Hosted by “The Voice” coach Kelly Clarkson, the “2018 Billboard Music Awards” will broadcast live from MGM Grand Garden Arena in Las Vegas on Sunday, May 20 at 8 p.m. ET / 5 p.m. PT on NBC. The three-hour telecast will feature performances from this year’s hottest musical acts, unexpected collaborations and buzzworthy moments that celebrate 60 years of the Billboard Hot 100. 

Nominations for the “2018 Billboard Music Awards” were announced last month on NBC’s “Today” and on a livestream from Billboard’s New York office. Kendrick Lamar, Bruno Mars and Ed Sheeran tie for the most nominations this year with 15 each. 

Voting for the two fan voted categories – Billboard Chart Achievement Award and Top Social Artist – will open on Monday, May 14 and additional details will be available soon.

“Billboard Music Awards” nominees and winners are based on key fan interactions with music, including album and digital song sales, streaming, radio airplay, touring and social engagement, tracked by Billboard and its data partners, including Nielsen Music and Next Big Sound. The awards are based on the reporting period of April 8, 2017 through March 31, 2018. Since 1940, the Billboard charts have been the go-to guide for ranking the popularity of artists, songs and albums, and are the ultimate measure of success in music.
