Fans have slammed a concertgoer who groped Nick Jonas while he was on stage in Los Angeles earlier this week.

In a video shared online, one fan can be seen grabbing Nick's leg and his bottom, before sliding her hand up the singer's leg during the Jonas Brothers' show at at The Hollywood Bowl.

As Nick pushes the fan's hand away while continuing to sing their hit Only Human, security attempts to move the overzealous fan away and tell them to stop.

While the singer has yet to comment on the incident, many fans have expressed their disgust and anger towards the person, calling them "very disrespectful".

"Dear @nickjonas on behalf of the rest of the fandom I really want to apologize for what happened at the Hollywood Bowl," one fan wrote in a heartfelt post. "No one should be touched like that without consent, by a stranger. I hope the rest of us can make it up to you by showing what respect is. #happinessbeginstour."

"They need to stop touching him PERIOD!" another added, while a third penned: "That is just crossing the line of boundaries."

Other angry users suggested the fan's actions verged on "sexual harassment" and "assault", while an impassioned devotee was clearly moved by the star's ordeal, posting: "I AM CRYING FOR @nickjonas he must be so upset I hope he’s okay."
