Maroon 5 performed Monday night in Anaheim, and one fan appears to have gotten a little too excited. She climbed up on stage and ran to hug Adam Levine while he was performing on the cat walk.

Here's a look from another angle. She was super excited, and you can see Adam is less than excited. He pushed her away at first, and then you can see tries to calm her down.

"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---ing in your face," Levine told the crowd. "It's super terrifying."

Showing appropriate levels of fan behavior is this little dude. He's my hero, and I want to be him one day when I grow up.
