Celine Dion is back with new music and better than ever.

The GRAMMY winner released a new single on Friday, featuring electronic violin sensation Lindsey Stirling. The song, "The Show Must Go On," is a cover of Queen's classic 1991 tune.

Fans can watch Dion and Stirling perform the song at the Billboard Music Awards on Sunday, where Dion will be honored with the ICON award. Past winners of the distinction include Jennifer Lopez, Prince, Stevie Wonder and Neil Diamond.

Sunday will certainly be a bright spot in Dion's year, which has been full of tragedy after losing her husband, Rene Angelil, to throat cancer in January, as well as her brother just a few days later. Earlier this month, she opened up to ABC News for her first television interview since Angelil's death, describing the somber, final moments with her husband of 21 years.

"You were worrying for my career. You were worrying for the children. You were worrying for everything. It's enough. Do you trust me?" Dion said she told Angelil. "Please do. Trust me. The kids are fine. I'm fine. I promise you we're gonna be OK. Please leave in peace. I don't want you to worry."

Dion went on to share how she and her three sons -- 15-year-old Rene-Charles and 5-year-old twins Nelson and Eddy -- have been coping without the patriarch.

"It's like I don't live with him physically, but I live with him inside of me," she told ABC News' Deborah Roberts. "I miss him when he was well. I miss him the way that I knew him, without the sickness."

The Billboard Music Awards air live May 22 at 8 p.m. ET/5 p.m. PT on ABC.
