This year's iHeartRadio Awards saw some huge names take home prizes - with the likes of Taylor Swift, Justin Timberlake, Hozier, Sam Smith and more crowned victorious.
On the same night that she joined Madonna to perform on stage, Swift continued the runaway success train of her latest album 1989, by winning three awards - for Song Of The Year, Best Lyrics and Artist Of The Year.
"I'm so proud of the fact that having done this for ten years now, we've gotten closer and closer with each year, not further apart," she said in her acceptance speech for Artist of the Year. "I love knowing your stories, thank you for joking around with me on Instagram and Twitter and Tumblr. You make me so happy."
Another huge success came for suited pop icon Justin Timberlake, who was given the Innovator Award by Tom Ford.
"Growing up in school, no-one ever called me anything close to an innovator," Timberlake said, accepting his award. "They called me different, they called me weird.
"If you're a young person like I used to be, and you're at home watching and you're being called weird or you're being called different... I'm here tonight to tell you your critics do not count."
He added: "Their words will fade, you won't. Dream and work hard, and maybe one day you'll find yourself standing on a stage and maybe someday somebody will be giving you an award calling you an innovator."
Meanwhile, Hozier beat Foo Fighters and Arctic Monkeys with 'Take Me To Church' named Alternative Rock Song Of The Year, Best Fan Army went to 5 Seconds Of Summer's 5SOSFam, and Sam Smith was awarded Best New Artist. Check out the full list of winners below.
