Since the incident went viral on Twitter, fans have been incredibly vocal.
"Treat band members how you wanna be treated. They aren’t toys. You wouldn’t do this if it was someone in the street."
Another fan wrote: "She went and touched him without his consent in a place that’s not hers to touch and it makes me so f*cking sick."
Neither Nick, Joe or Kevin have spoken out about the incident, but it's an important reminder that touching anybody without consent is a big no-no, even if they're celebrities.
A similar encounter happened to Billie Eilish in May, when she was doing meet-and-greets, having to publically ask her fans not to grope her anymore.
"Pls don’t grab my boobs in the meet & greet," Billie wrote. "I try very hard to make everyone happy at the m&g, but sometimes you make it very difficult for me to feel comfortable enough to do that."
Most famously would be Taylor Swift's groping incident that she won in court.
Former radio DJ David Mueller sexually assaulted the "Lover" singer when he groped her butt during a meet and greet.
One year later, the star celebrated her win during a concert.
"This exact day, a year ago, I was not playing a sold-out stadium in Tampa; I was in a courtroom in Denver, Colorado. Honestly, I was there for a sexual assault case and this day, a year ago, was the day that the jury sided in my favour and said that they believed ME. I really— I’m not— I don’t wanna— I guess I just think about all the people who weren’t believed and the people who haven’t been believed and the people who are afraid to speak up because they think they won’t be believed. And I just wanted to say I’m sorry to anyone who ever wasn’t believed because I don’t know what turn my life would’ve taken if people didn’t believed me when I said that something had happened to me.
"So I guess I just wanted to say that we have so so so much further to go and I’m so grateful for you guys for being there for me during what was a really, really horrible part of my life. So I just wanted to say that and I wanted to thank you for everything."
