A list of the winners at the 2017 American Music Awards, held Sunday night at the Microsoft Theater in Los Angeles. Mars also won video of the year and favorite male artist, pop/rock, and favorite album, pop/rock.
Oscar-winning American actor, and rocker of the band Thirty Seconds To Mars, Jared Leto, who went on stage right after BTS' performance said, "I need a moment to recover from that performance".
The 73-year-old was cheerful and energetic as she ran through well-known songs onstage like a veteran, singing I'm Coming Out and Ain't No Mountain High Enough, among other hits, with her signature big hair.
Besides thanking the fans for their support, BTS promised to return to the U.S. for future shows and performances.
The American Music Awards opened the night with a tribute to first responders of recent natural disasters and tragedies. First responders stood behind Jamie Foxx, who gave a heartfelt speech before the pop stars sang R.E.M.'s Everybody Hurts.
The two singers had never met before the dress rehearsal but when they finally hit the AMAs stage at the beginning of the ceremony, their duet was flawless, wowing the audience and landing them a standing ovation.
While the performers at the AMAs were evenly split between men and women, the nominees were not - a reflection of the year in pop music where male acts dominated. Julia Michaels is the only woman up for new artist of the year.
Two of the music world's strongest women combined forces for the first time on Sunday night in one powerful duet. No woman hit the top of Billboard's Hot 100 chart in 2017 until Taylor Swift and Cardi B did so in September. At the 2017 edition, the most awarded artist was Hawaii's very own Bruno Mars, who took home a total of 7 trophies.
