Kendrick Lamar got a little more than he bargained for when he brought a girl from the audience onstage to perform with him Sunday during the Hangout Music Fest.
After getting her ready to rap "M.A.A.D City", she decided, we assume, that this gave her the rights to sing the song as he recorded it. After a first pass, and boos from the audience, he stopped her and clarified that she needed to "bleep" one word.
Against the jeers from the crowd, he gave her another chance, and she just couldn't control herself. So he stopped the song and escorted her off the stage.
