The 2018 Billboard Music Awards paid tribute to the students and teachers affected by recent deadly shootings in Texas and Florida, while the night also featured show-stopping performances by iconic singer Janet Jackson and K-pop group BTS.

A tearful and emotional Kelly Clarkson, who hosted the awards, opened the show in honor of the 10 people who died Friday at Santa Fe High School, barely able to speak as she urged the audience and the world to do more to prevent deadly shootings from happening. She said she was asked to hold a moment of silence, but chose instead to call for "a moment of action."

"Once again we're grieving for more kids that have died ... I'm so sick of moment of silences ... it's not working," she said Sunday, almost in tears. "Mommies and daddies should be able to send their kids to school."

Shawn Mendes and Khalid were joined onstage by the Marjory Stoneman Douglas Show Choir for the song "Youth," a performance occurring three months after 17 people were killed at the school in Parkland, Florida.

Mendes and the choir members wore sweaters that read "Youth," while Khalid's shirt read "Protect Our Guns Children" with "Guns" crossed out.
