When Kanye West got on stage Saturday night during 102.7 KIIS FM's Wango Tango at the StubHub Center in Carson, Calif., he wasn't expecting everyone to leave before his last performance.
During the performance West announced that he was about to sing his hit song "All Day," but warned that it wasn't going to be the radio version, reported Hollywood Life.
The concert also had other singers and performers - including Justin Bieber, Nick Jonas and Fifth Harmony - who draw in a younger audience.
Once West started singing "All Day," which was filled with the N-word, floods of people started exiting the stadium.
"The stadium holds 27,000 people and hordes of them left. He did not edit himself at all, and parents were visibly pissed," an unnamed source told Hollywood Life.
The source said a lot of parents regretted not leaving as soon as Bieber was done performing.
The Wango Tango concert on May 9 was the 17th annual year of the popular Los Angeles-area show.
