Will Drake or the Chainsmokers be the night’s big winners — or will the boy band BTS be the group that everyone is talking about?

For that, you’ll want to tune into ABC to watch the 2017 Billboard Music Awards live from the T-Mobile Arena in Las Vegas 5 p.m. Sunday May 21. And to give you a head start on all the trivia you’ll be soaking in, here are 5 things you should know.

Ludacris and Vanessa Hudgens are this year’s co-hosts: It’s the fourth consecutive time that Ludacris has reigned over the event and Hudgens’ first.

Prince Jackson is coming: Michael Jackson’s eldest son will be one of the award presenters. Others include Kevin Hart, Olivia Munn, Hailee Steinfeld and Josh Duhamel.

Drake and The Chainsmokers are tied: These two acts share the all-time record for most nominations in a single year with 22 each and are going up against each other in 10 categories. Twenty One Pilots has 17 nominations and Rihanna has 14.

BTS is representing: The group is nominated for Top Social Artist, a category whose winner is determined by fans’ votes. The boy band’s album, “Wings,” entered the Billboard 200 chart at No. 26, which is the highest chart position for any K-pop act. What makes this even more interesting is that the group sings primarily in Korean.

Imagine Dragons will honor Chris Cornell: The group will share how he influenced them though they aren’t scheduled to perform any of his music. The special moment is among the performances to catch during the show, such as Bruno Mars, Nicki Minaj, Ed Sheeran, Celine Dion and Florida Georgia Line.
