The 2017 Billboard Music Awards airs live from the T-Mobile Arena in Las Vegas on Sunday, May 21 at 8 p.m. ET/5 p.m. PT on ABC.

ET caught up with Dion backstage at last year's Billboard Music Awards, where she opened up about performing Queen's "The Show Must Go On," which was her late husband's "favorite song."

"To try to perform that song without collapsing was big enough," she explained, "and then I turned around and I saw my son. As a mother, I really, through this whole process of our new life, wanted to be strong."

"I thought I was going to make it through the whole night without tears and show strength, and love won," she said. "I just collapsed. I'm very thankful for the award and proud of my family so much."
