The Dolby Theatre in Los Angeles came alive with some of music’s biggest stars Monday night (March 17), with Billie Eilish, Benson Boone and Gracie Abrams all winning big at the 2025 iHeartRadio Music Awards.

Among the prizes given out were album of the year, which went to the “Birds of a Feather” singer’s Hit Me Hard and Soft; song of the year, which the Missouri-born pop-rock prodigy took home for his smash “Beautiful Things”; and breakthrough artist, which the “That’s So True” musician accepted. SZA also won R&B artist of the year for a record third year in a row, while Jelly Roll nabbed country artist of the year and GloRilla snagged hip-hop artist of the year. Plus, Lady Gaga was honored with the 2025 iHeartRadio Innovator Award, and Mariah Carey received the 2025 iHeartRadio Icon Award.

And in between accepting their respective awards, all of the musicians on hand at the L.A. venue also got the chance to brush shoulders, say hi to old friends and introduce themselves to new pals at the ceremony. Many of the best moments were captured in photos behind the scenes, with Bad Bunny and Becky G posing together backstage, Glo, K Carbon and Sexyy Red getting cheeky in matching gold outfits and winners such as Boone and Carey showing off their new hardware for the cameras.
