The incident went down on October 21 during the Jonas Brothers' Happiness Begins Tour at the Hollywood Bowl in Los Angeles.
The video of the groping was captured by a fan and has started going viral.
Look But Don't Touch
Many fans expressed how wrong the fan was for the unwanted touch and some felt ashamed that there is a JoBro fan that would act that way.
"That IS sexual assault," one fan commented, "She went and touched him without his consent in a place that's not hers to touch and it makes me so fcking sick."
The video shows the brothers surrounded by the crowd and a rambunctious fan can be seen reaching out to touch Nick's leg, butt, and nether region.
Security Tried To Stop Them
Security can be seen trying to stop the fan but the perpetrator did not quit until Nick turned around to scold them.
"He was maaad," a concertgoer noted, "Everyone knows he doesn't like being touched!"
Keep It Movin'
Nick did not even acknowledge the incident publicly and it seems like he does not want the groping to taint the Hollywood show.
"Hollywood Bowl night 2. Thank you to every single one of you who made these two sold out nights so incredible," Nick wrote on Instagram. "I am so grateful."
Nick, Joe, and Kevin have to put this incident behind them because they are slated to play two shows in Monterrey, Mexico as the tour continues.
