What to expect from the 2017 American Music Awards

— -- The American Music Awards are perhaps best known for their musical performances, and according to this year's host and producers, there'll be no shortage of memorable, touching and even "insane" moments.

The excitement will start right away, with Kelly Clarkson and Pink opening the show with a duet.

"It’s [Clarkson's] 15th anniversary of winning 'American Idol,' so she’s gonna throw it back to her very first hit, as well as doing her newest single," AMA producer Mark Bracco told ABC News. "And then Pink ... is doing something that has never been done before ... and it’s insane in the best possible way."

Selena Gomez's performance of "Wolves" is sure to be a highlight for fans as well. The singer will be taking the stage for the first time since her kidney transplant, and Bracco said that it's bound to be "a very emotional night for her."

Another highlight: Christina Aguilera will sing a medley of songs from Whitney Houston's "The Bodyguard" soundtrack, released 25 years ago this week.

"Black-ish" star Tracee Ellis Ross hosts the show, and she's most excited for the performance by her mom, the iconic Diana Ross, who will receive this year's Lifetime Achievement Award.

"There’s so much of an emphasis on youth, but to see a woman whose career has spanned so many decades, that is still performing, still on stage, still singing live, still looking gorgeous ... it shows you what’s possible," she told ABC News. "And people who’ve never seen her ... it’s worth it!"

The American Music Awards air live on ABC Sunday night at 8 p.m. ET. Other performers include Niall Horan, Alessia Cara, Demi Lovato, Lady Gaga, Shawn Mendes, Hailee Steinfeld, Nick Jonas and many more.
