But there may have been no bigger fan in the house than Celine Dion! Last year was a great moment for me here receiving the Icon award, but this year was like "I'll go".
Under a glittering chandelier and dressed in a Met-worthy white gown, Dion wowed the audience with her performance and earned one of the biggest cheers of the night.
Accepting the Billboard Icon Award from Gwen Stefani, she gave a short but poignant speech remembering her 53 years in the music industry.
Nicki also appeared to get jealous over the show's host Vanessa Hudgens when Drizzy called her "incredible" during his first acceptance speech of the evening.
Halsey's tan bralette top that she paired with an unbuttoned thigh-high khaki skirt did not really make the cut. As the crowd roared with delight, Cher delivered a nostalgic performance of her 1989 hit "If I Could Turn Back Time". "And I can do a five-minute plank, just saying".
The seven-member group accepted the Top Social Artist award during the 2017 Billboard Music Awards at the T-Mobile Arena in Las Vegas, Sunday, beating big-name American competitors, such as Justin Bieber, Selena Gomez, Ariana Grande and Shawn Mendes.
Two decades after a movie and a song captivated the country, Celine Dion revisited her iconic hit "My Heart Will Go On", with the same passion as ever. "Cher remains one of the most prolific performers of all time". The performance was in celebration of the song's 20th anniversary.
Released last week, Cyrus' new Malibu single has been heralded as the start of a new era for the singer, leaving behind the hip hop influences of her 2013 album Bangerz and the hippie-provocateur image of her Dead Petz phase.
