Ariana Grande won the American Music Award for Favorite Female Artist in the pop-rock genre Sunday night. The 22-year-old singer accepted the award, presented by Paula Abdul and Donnie Wahlberg, shortly after performing her latest single, “Focus.”

Grande was flustered when she got behind the microphone at the Microsoft Theater in Los Angeles. After saying “oh my God” several times, the “Problem” singer said, “Hi Paula.” Grande seemed excited to meet the former "American Idol" judge, but she was more concerned with thanking her fans.

“I really have no idea what to say,” Grande said. “I didn't think about this part. This is for my fans. I have the most incredible fans. ... Ew, I'm crying. I love you guys. Thank you so so much.”

She was also sure to acknowledge her family during her AMAs speech. “I think I owe a lot of this to my Nonna, who made sure to remind me that she voted,” Grande explained. “She goes, ‘Ariana, I went on the computer and I voted, so I think you’ll win.’”
