Let's just say, Dion and her fans reunited with a vengeance in Vegas in 2003 and were hardly ever apart again.

Sadly, Angélil was again diagnosed with cancer in 2013, and in August 2014 Dion canceled the remainder of her shows for the year. She wouldn't perform again in Vegas for a year.

Angélil died on Jan. 14, 2016, and after a few weeks off, Dion returned to the stage with a show dedicated to her husband. And he remains by her side, albeit in a different way.

"It's been a tough journey," Dion told E! News in July 2016. "Like I say, many times, many people go through this, and you see your husband suffer for three years, and it's not what you want to see. So now I know he is well, and we live with him in a different way. And I see him through the eyes of my children every single day."

On Oct. 8, 2016, she played her 1,000th show in Vegas.
