Crazy Fan Rushes Maroon 5 Stage, Jumps All Over Adam Levine [VIDEO]

Women LITERALLY throw themselves at Adam Levine. Levine is not impressed.

While performing in Anaheim, CA last night, some super fan... an Adam Levine fan... I don't know what she is, probably drunk, but a girl rushed the stage and grabbed Adam Levine from behind.

Levine bobbed and weaved trying to get away before just embracing the crazy girl.

Levine said, "That was f--king weird, right?"... "She like, cut my ear with her fingernail... 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--king in your face. It's super terrifying."

How did the fan get on the stage in the first place? Strong security...
