The show is airing live on TBS, TNT and truTV from the Forum in Inglewood, Calif.

Before Noah Cyrus and Labrinth took the stage at Sunday's iHeartRadio Music Awards for her award show debut, her big sister Miley Cyrus walked out flaunting an "I [heart] Noah" shirt and poster, pumping up the audience by yelling, "Get ready 2017! It's going to be Noah's year!"

The 17-year-old singer, performing with Labrinth, opened the performance of her song "Make Me (Cry)" in a red jumpsuit with a heart on her crotch area and a heart cut out on her crop top, matching with Labrinth's jacket. 

The artists kept their first award show performance simple, staying within a few feet of each other with lights shooting to the ceiling, making it look like a jail cell. While the singers mainly stayed put, the lights made the performance pop.

Other performers of the night included Bruno Mars, Big Sean, Shawn Mendes, Ed Sheeran, Chris Martin and The Chainsmokers.
