Ariana Grande released her latest single “Focus” on Thursday, and revealed Friday that the track features a special vocal guest: Jamie Foxx.

Grande performed at the iHeartRadio Theater in Los Angeles, and before the show she gave a Q&A. When asked who the male voice was, she answered Foxx.

The Q&A took a bizarre turn, though, when an audience member threw a phone at Grande. “Did someone throw a phone at me?” she asked. “Did someone just throw a phone on stage? That’s so dangerous. What if your screen cracked?” (See the whole altercation in the video below.)

The show also marked the first time she performed “Focus” since its release. “[The song] sounds like ‘Problem’s older sister,” she told the crowd, referencing her 2014 hit. It’ll be featured on her 2016 album, Moonlight.
