Nick Jonas was groped by a fan while performed during a recent Jonas Brothers concert.

The youngest JoBro found himself in an uncomfortable situation at their Happiness Begins tour stop in Los Angeles on Monday (October 21) when a female fan repeatedly rubbed his leg and tried to grab his butt. In a video captured by a concertgoer, you can see Jonas trying to stop her, but she touched him anyway.

Security also got involved and tried to get her to stop, but again, she was relentless. At one point, the singer even turned around to give her a look and was so close to the edge of the stage that he almost fell off.

It's unclear if she was asked to leave (because the video ends before we find out), but hopefully, she was removed from the stage. It's so inappropriate to touch a person without their consent... even if it's a Jonas Brother.

After the video was posted to Twitter, fans expressed their anger toward the unknown fan. Many defended Jonas and called out the woman for being disrespectful.

"This is honestly so hard to watch," one person tweeted. "Can they not get it through their heads that Nick is clearly uncomfortable as he turns back to look at them and tried to swat their hand away? Ugh, this is not how you should treat them. They're people just like us who don’t need to feel violated."
