The American Music Awards aired Sunday night and everything from questionable fashion choices to scandalous performances gave viewers much to talk about.

Perhaps the biggest talker of the night was Rihanna‘s performance of her song “Diamonds” followed by an appearance from her mother, who presented her with her first-ever Icon Award.

“My fans, I love you so much; you have no idea,” Rihanna said. “I can’t believe at 25, I am holding an Icon Award!”

Meanwhile, her hairdo, which was wrapped around her head and decorated with hair pins,  was another topic of discussion.

Other unforgettable moments made jaws drop as Lady Gaga and R. Kelly took to the stage to sing their duet “Do What You Want” in a performance that was far from tame.

Meanwhile, Justin Timberlake‘s soulful rendition of his song “Drink You Away” had almost every audience member on their feet and clapping in tune with the beat.

Jennifer Lopez brought tons of Latin flavor with her performance tribute to the “Queen of Salsa,” Celia Cruz. Lopez rocked the stage and sashayed the night away.

Kendrick Lamar also showcased his talent last night when he performed his song “Swimming Pools.” He was nominated for the favorite rap/hip-hop album award but instead, it went to Macklemore and Ryan Lewis for The Heist.

Upon accepting their award, Macklemore delivered a powerful speech in which he referenced  the late Trayvon Martin and Dr. Martin Luther King.
