Nick Jonas talks about his 'worst moment' on stage: 'It did cause me to go into therapy'

Nick Jonas still remembers his on-stage screw-ups — even the ones from decades ago.

On Monday's episode of Dax Shepard's "Armchair Expert" podcast, Jonas recounted a few moments where he "blacked out" on stage. "I actually view them as core memories," the singer said.

“I spent weeks thinking about how I could have better handled the situation, and looked more like a pro,” Jonas, now 30, said of one performance when he was "17 or 18."

"Then there was another time during a really tragic guitar solo debacle that happened on live TV," the pop star went on, describing what he called his "worst moment." "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 into therapy."

The moment happened when Jonas was a guest performer at the 2016 ACM Awards, and performed "Peter Pan" with Kelsea Ballerini.

"I rehearsed it a million times," the singer said. At the beginning, he was "feeling really confident about it."

"I started off, it's fine and as I walked towards (Ballerini), 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."

Jonas still isn't quite sure what caused the blackout. "To this day and hours of unpacking (it), I can't really figure out exactly what happened."

"I looked at my manager and said, 'I think that was bad,'" the star recalled. "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."

Jonas is no stranger to therapy.

In past interviews, the singer has also talked about how therapy helped him reunite with his brothers ahead of their 2019 comeback release "Happiness Begins." In a chat with James Corden on "The Late Late Show" in March of that year, the singer talked about how he and his brothers went to therapy together before releasing new music together.

“We literally spent a year basically doing therapy, working through some things, and figuring out what this chapter would look like,” Jonas said. “We’ve had to be really open and honest. There are things in the past that bothered us from time to time, even in our performances that we would do.”

That honesty made it possible for the brothers to play music together again after a five-year hiatus. "There was a magic that we felt like we were missing,” Jonas added of their reunion.
