After Ballerini belted out her part of Peter Pan, Nick claimed the stage with his electric guitar and did a painful guitar solo.

‘A really tragic guitar solo debacle … happened on live TV,’ shared the S.O.S. singer. ‘In retrospect, I can kind of laugh about how big I thought it was. But it did travel more than I wish it would have, and it did cause me to go to therapy.’

Nick’s nightmare: Nick Jonas, 30, got candid on Monday with Dax Shepard when he opened up about his all-time ‘worst moment’ on stage

Painful: The musician sat down with Shepard for his Armchair Expert podcast and revealed that a ‘tragic’ performance with Kelsea Ballerini sent him to ‘therapy’

The Jonas Brother took Shepard through his nightmare point by point, saying that the disaster happened even though he rehearsed the guitar solo ‘a million times.’

Nick said: ‘I come out for my thing. I rehearsed it a million times. I’m feeling really confident about it — not even really thinking about it like it’s a thing that’s going to be problematic.

‘I started off, it was fine and as I walked towards her, I just went completely blank and I hit a wrong note and blacked out basically and clocked that it was wrong and I couldn’t stop.’

The Sucker singer – who watched his wife Priyanka Chopra win the 2000 Miss World Pageant when he was seven years old – got roasted for the botched set on social media as it turned into a viral flub and made Nick the butt of endless online jokes.

Merciless fan tutorials on how to play the wrong version of Kelsea’s song Peter Pan became a particular low point for Jonas, who tried to have a sense of humor through the ordeal.

Tweeting about the backlash at the time, he wrote: ‘Just landed in London to all these posts from Sunday nights performance. So funny. Yes, I screwed up the solo thanks to a huge brain fart.’

The hitmaker also retweeted a mock sheet of music that lampooned his performance, writing: ‘We’re all human and s—t happens sometimes, but whoever made this is a genius.’

Speaking to Shepard, the Camp Rock star confessed that he ‘can’t really figure out exactly what happened.’

Yikes: The infamous ‘debacle’ happened in 2016 when Nick teamed up with Kelsea to perform her hit song Peter Pan at the Academy of Country Music Awards. After Ballerini belted out her part of Peter Pan, Nick claimed the stage with his electric guitar and did a painful guitar solo

Priorities: Ahead of their upcoming tour, Nick and his brothers have revealed that they are prioritizing their mental health; pictured on the Today show earlier this month

Nick told Dax: ‘I looked at my manager and said, “I think that was bad.” I was, like, in shock kinda. It was a really traumatic moment that shaped the pressure I put on myself to be perfect and to always be on.’

But there’s no hard feelings between Jonas and Ballerina, as the country singer remains a ‘huge fan’ of the former teen idol.

‘I’m a huge fan of him,’ Kelsea told The Hollywood Reporter. ‘I was a huge Jonas Brothers fan, unapologetically, when I was 12 or 13.

‘His solo stuff is just incredible and it was really cool to collaborate with him on the awards. I’d totally do more with him if I could.’
