Ariana Grande is riding high with the success of her collaboration with Iggy Azalea, “Problem,” but she’s already looking ahead to her next.

“I did a song with Zedd, who I just met for the first time,” the singer explained at Saturday’s Wango Tango. “I really want that to be the second single. My whole team is like, ‘Oh, it’s too early to pick a new single,’ but I’m really … I love that song so much. He’s fantastic and the song is really fun, and it’s very different for me especially.”

Until her second single drops, catch Ariana and Iggy when they perform their big hit at the Billboard Music Awards, which airs this Sunday at 8/7c on ABC.
