The tense incident was caught by the hundreds of cameras held by fans in attendance.
Levine admitted to the crowd that the incident was scary.
"It's just weird to be, like, in the moment, ya know? And you're singing, and your eyes are closed, and you have this beautiful moment. And then the next thing you know someone's f*cking in your face," Levine told the crowd. "It's super terrifying."
The Voice coach also said that he even got a cut on his ear from the woman's finger nail, but continued the show after the fan had been removed.
Concert goers quickly took to Twitter and Instagram after the event, with many blaming fans like that for added security measures that keep the audience farther from the stage at concerts.
Others just couldn't believe what happened.
