Read on for some of the biggest moments from the 2021 AMAs!
Silk Sonic Opens the Night in Style
Bruno Mars and Anderson .Paak kicked off the show with a bang, performing as duo Silk Sonic for a smooth, stylish number. Rocking crimson leisure suits and belting out a fan-pleasing performance of their smooth hit "Smokin Out The Window," the pair set the bar high for the rest of tonight's performers.
Cardi B Is Just the Best and Realest
The "WAP" rapper made her hosting debut at this year's show, where she brought down the house with a dramatic ensemble and her signature humor. "Damn this crowd is loud," she belted as she welcomed everyone to the 2021 AMAs. "I ain't gonna lie. I'm a little nervous. I'm sweating."
Later in the night, Cardi used her public platform to convince JoJo Siwa to come to her house this Christmas to delight her kids and JoJo had little choice but to enthusiastically agree. With Cardi as host, it feels like you never truly know what's going to happen!
Olivia Rodrigo Brings the Feels
The 18-year-old singer stirred the emotions of everyone in the theater with her stripped-down, powerful performance of her single "Traitor." With a guitar in hand, Rodrigo made her debut on the AMAs stage, delivering an acoustic version of the heartbreak ballad, letting the song's gripping lyrics do the talking. Kicking things off in a free-standing doorway and surrounded by a field of flowers on stage, Rodrigo crooned the tune in a beautifully simple and delicate pink dress and toned-down makeup.
Bad Bunny Goes Sci-Fi
Bad Bunny, Tainy and Julieta Venegas went sci-fi and high-tech with their futuristic performance of "Lo Siento BB," which is featured off of Tainy's debut album, Data. With Venegas' face appearing on the front of a cyberpunk-esque robot pianist and Bad Bunny rocking a sleek, all-white outfit with a head-covering mask featuring a HAL-9000-like red light on the front, every bit of the number was captivating.
Chlöe Defies Gravity
Every time Chlöe has hit the stage at an awards show since starting off on her solo path, she's been making moments and delivering real spectacle. For her performance of "Have Mercy" at this year's big show, Chlöe kicked off the number by descending from the rafters on wires like an angel descending from heaven -- then delivered one of the most masterfully and impressively risqué performances of the night that proved how much star power she truly possesses.
Jennifer Lopez Is Angelic
The celebrated songstress and actress took to the stage to deliver the debut performance of her new song "On My Way," which also serves as the main song for her upcoming romantic comedy, Marry Me. The 52-year-old superstar began her performance in a dramatic black gown sitting at a piano. She then did a quick and stunning outfit change, wearing a beige tulle dress with a veil. Scenes from the film flashed behind her as she belted out the deep lyrics.
Mickey Guyton Inspires and Delights
It was unclear whether or not the Remember Her Name artist would even be able to perform at this year's show, after her her son, Grayson, suffered a scary health issue earlier in the week that required him to spend time in the ICU. However, it seems that Guyton's little boy has recovered, and the powerful country songstress delivered an incredible performance of her moving and inspiring tune "All American," which earned a standing ovation from the audience.
The Battle of Boston Brings Boy Bands Together
For the first time ever, New Kids on the Block and New Edition shared the stage! The boy band and R&B group brought their A-game to the show to deliver some of their biggest hits. NKOTB kicked off the so-called "battle" with a performance of "The Right Stuff," which New Edition followed with a flawless delivery of "Candy Girl."
NKOTB came back with "Step by Step" and "Mr. Telephone Man." The two groups then joined forces at the end to combine "Is This the End" and "Please Don't Go Girl," before New Edition took over again and sang "Can You Stand the Rain." Seeing the two groups come together was a real thrill.
NKOTB's Donnie Wahlberg spoke with ET's Cassie DiLaura on the red carpet ahead of the big show, and said, "It's surreal. Being here is always fun, but to be here with New Edition, who mean so much to us and really paved the way for us, and all boy bands. It's kind of a boy band night, and it wouldn't be right to be here without the real guys who created the modern boy band."
Zoe Wees Is a Vocal Powerhouse
The German pop star commanded the stage in the night's penultimate performance as she served up a moving and impressive delivery of "Girls Like Us." Surrounded by back-up dancers on a minimalist stage, Zoe proved you don't need more than lyrics and a stunningly unique voice to steal the spotlight.
BTS Closes Out the Night Just Right
After a silky smooth opening number from Silk Sonic, BTS delivered a smooth, fun, upbeat performance of "Butter" to close out the star-studded show. As always, the band delivered the moves and charm that have made them next-level megastars, and the performance served as a great cap to their big night, where they took home three awards for Artist of the Year, Favorite Pop Duo or Group, and Favorite Pop Song -- which they earned for "Butter."
