So scary! Adam Levine was completely caught off-guard when a fan jumped onto the stage and grabbed him during a recent Maroon 5 concert.

In the video, which you can watch above, Adam is caught up in the moment, when a fan pulls herself onstage and runs at him. She grabs him from behind before he even knows she's there. Adam jumps back before trying to calm the fan. He kindly puts his arm around her as security runs up to intercept.

Afterward, Adam told the crowd, "That was f---ing weird, right? ... She cut my ear with her fingernail.”

“It’s just weird to be, like, you’re in the moment, you’re singing, and your eyes are closed, and you’re having this beautiful moment, and the next thing you know someone’s in your face," Adam added. "Super terrifying."

This isn't the first odd fan interaction during a Maroon 5 concert. During a recent show, Adam accidentally hit a fan on the head with a microphone. The incident was also caught on video, along with Adam apologizing to the crowd and saying, "When I was trying to get everybody to pay attention, it was because I felt so utterly terrible that I had perhaps wounded this young fan. So I brought her onstage, ran a little distraction so we could get our s--- together, and she is now enjoying the concert from the side of the stage, as she should be. What we’re going to do is, we’re going to pretend none of that happened.”

You can watch Adam get stage-rushed in the videos above and below.
