The 2016 Billboard Music Awards was held Sunday night at the T-Mobile Arena in Las Vegas, Nevada where there were some incredible performances, most notably from Céline Dion.

Dion, who lost both her husband René Anglil and brother Daniel earlier this year, broke down in tears after her son René-Charles made a surprise appearance to present her with the Billboard Icon Award.

Dion was clearly on an emotional edge, but still performed a phenomenal cover of Queen’s 1990 song “The Show Must Go On.” It was Dion’s first time performing on TV since her tragic losses.

During her acceptance speech, she told the audience “I don’t want to cry in front of you, you make me so happy.”
