Grande was not physically at the award show.
Pharrell Williams told fans that the singe was days away from touring.
Instead she pre-taped both the performance and her acceptance speech.
"I am so honored," Ariana said, holding the award.
"I will sleep with this tonight."
"Thank u @iheartradio for having us on the show," she wrote on her Instagram at the end of February.
"We’re so honored and excited for u to hear what we did and to be there in spirit (just know that while you’re enjoying our televised performance i’ll be running around like a fucking maniac during our final dress rehearsals)... tune in march 14 🌫 love u."
Someone who was the show was Taylor Swift... Watch her dramatic entrance!
