He said: "The most important thing is people who will say no, you must have people around who say to you," Look, if you do that, people will think you are a jerk. "They are my guardrails.

"I grew up in adolescence in the area, but I sometimes felt that I was going to get out of hand. I love so much music and my career. So that everyone could go that far, when I was younger, when I weighed the options like: "Right now, am I going to regret it?" I've always chosen music.

Jesse is away from the spotlight to spend time with Katie and create memories outside concert halls and venues.

Speaking of his break with the spotlight, he added, "Often you travel the world as a musician and you never have a chance to see the world. You are always inside a place or a hotel.

I wanted to travel, immerse myself in culture and learn a little more about myself. Discover my interests outside of music, understand what I like to read, what I like to learn and what my hobbies are. & # 39;
