You'll heart these celebrities.

After all, the 2025 iHeartRadio Music Awards was the place to be on March 17, with chart-toppers and performing powerhouses from across the nation descending upon the The Dolby Theater in Los Angeles.

Among the early arrivals were JoJo Siwa, who hit the high note—quite literally—in a towering headpiece featuring a bejeweled orb dangling in the center of a larger circle. She completed the head-turning look with a pink Versace bra top and matching underwear sticking out from her jeans, as well as a bedazzled denim jacket.

Meanwhile, Benson Boone looked like he was ready for a night of music and dancing, rocking a black lace button-up shirt paired with white trousers.

And this year's ceremony—hosted by LL Cool J—is all about celebrating musicians who pushed boundaries. Take Taylor Swift, whose sold-out Eras Tour is being awarded the Tour of the Century prize after earning a record-breaking $2 billion in ticket sales alone.

The "Lavender Haze" singer is also leading the pack of nominees with 10 nods, including Artist of the Year, Pop Artist of the Year and Favorite Guest for boyfriend Travis Kelce's surprise onstage appearance at the London stop of her tour.

But she isn't on her own, kid. Country music superstar Morgan Wallen is also heading into the ceremony with 10 nominations, while Sabrina Carpenter, Kendrick Lamar and Post Malone have nine nods each.

As for this year's Icon Award? Mariah Carey will join the ranks alongside past recipients Cher, Pink, Jennifer Lopez, Elton John and Bon Jovi. 

And get ready to shower Lady Gagawith applause—because the "Abracadabra" singer will be receiving the Innovator Award, which had been previously given to the likes of Beyoncé, Justin Timberlake, Pharrell Williams, Alicia Keys and Bruno Mars.

But trophies aside, Billie Eilish, Bad Bunny, Gracie Abrams, GloRilla, Kenny Chesney, Muni Long and Landmark Award winner Nelly will all be hitting the stage to perform.
