It was all about musical icons at the 2017 Billboard Music Awards.
Cher and Celine Dion showed everyone how it's done at this year's Billboard Music Awards with epic performances celebrating their careers.
Cher was honoured with the Icon award at the ceremony, and took to the stage to sing her hits 'Believe' and 'If I Could Turn Back Time'.
The 71-year-old recreated some of her most famous looks as she wowed the crowds with her flawless routine.
Accepting her award, Cher said: "I have wanted to do what I have wanted to do since I was four years old.
"I think luck has so much to do with my success. I think it was a little bit of luck and something else thrown in that had a little bit to do with my success."
Meanwhile, Celine brought the house down with a stunning rendition of 'My Heart Will Go On', which received a standing ovation.
The performance at the T-Mobile Arena in Las Vegas marked the 20th anniversary of Titanic, the movie she famously soundtracked.
It seems the two legendary performers have a mutual respect for one another, as Celine was spotted dancing away to Cher's performance backstage.
Elsewhere at the event, Drake was the big winner of the evening, breaking Adele's record to become the biggest single year winner ever.
His 13 wins included Top Artist, Top Male Artist and Top Hot 100 Artist.
But it seems even Drake isn't immune to becoming starstruck in the presence of musical royalty after he was photographed bowing down to Queen Celine backstage.
