The She Will Be Loved hitmaker was performing at the Honda Centre in Anaheim when a girl climbed up and grabbed the bewildered singer before security guards pulled her away.

Once the girl was escorted from the stage, Levine told the crowd, "It's just weird to be in the moment, you 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."

The group's tour concludes in New Zealand in October (15).
