AMAs 2017: Linkin Park wins for favorite artist after tragic death of lead singer Chester Bennington

Christina Aguilera also performed a tribute to "The Bodyguard."

Diana Ross honored for a lifetime of supreme talent

The elder Ross also received the evening's lifetime achievement award. And she did it in style, performing a medley of her most iconic hits, including "I'm Coming Out," "Ain't No Mountain High Enough" and "Ease on Down the Road."

Linkin Park was awarded the American Music Award for Favorite Artist - Alternative Rock just four months after the death of lead singer Chester Bennington.

The late singer's band members dedicated the award to Bennington.

"We want to dedicate this award to him, to his memory, to his talent, to his sense of humor, to his joy," Linkin Park co-founder Mike Shinoda told the audience. "And remember you guys, all of you -- whether you’re a fan or an artist -- take a moment to appreciate what you’ve got and make Chester proud."

A night of show-stopping performances

After her performance, Aguilera had a message for the late Houston, who has won the most American Music Awards ever with 21. "Thank you Whitney Houston for being the best inspiration ever," she said.

But the top award? That went to Bruno Mars, who sent a video message to receive Artist of the Year.
