American rap-rock star Post Malone was the biggest winner of this year's Billboard Music Awards by taking nine awards, including the heavy-weight top artist, top male artist, top rap artist, top rap album, and top Billboard 200 artist.

Held at the empty Dolby Theater in Hollywood on Wednesday, the three-hour awards ceremony was televised and broadcast online due to the ongoing coronavirus pandemic. The ceremony was originally slated for April 29.

Following Post Malone was singer and songwriter Khalid, who picked up five awards, including top R&B artist, top R&B album, and top R&B tour.

With her debut collection "When We All Fall Asleep, Where Do We Go?," Billie Eilish took home the top Billboard 200 album after it won the Grammy award earlier this year. She also gained the top new artist and top female artist.

Facing a virtual audience, Malone and Tyla Yaweh performed the songs "Circles" and "Tommy Lee," while John Legend, Doja Cat, Demi Lovato and others brought their popular singles or new songs.

K-Pop sensational band BTS won the top social artist and performed their hit single "Dynamite."

The Billboard Music Award is given out annually by the publication and music chart Billboard. Its finalists are based on album and digital songs sales, streaming data, radio airplay, touring, and social engagement.
