"I think I was nervous because I was afraid of what people are thinking about me right now," he explained in the video. "It’s been a minute since I’ve been in a public appearance, and I didn’t want to come off arrogant or conceited or basically how I’ve been acting the past year, year and a half," he said.

"I’m not what I was pretending to be. Why I say I was 'pretending' is often we pretend to be something we’re not as a cover up of what we’re truly feeling inside. And there was a lot of feelings going on in there," he continued. "Just being young and growing up in this business is hard. Just growing up in general is hard," he added.

"I just felt awkward up there. I felt like people were judging me, and I really want people to know how much I care, how much I care about people, and how I’m not that person to say, 'I don’t give a f---,' you know? I’m not that kid, I’m a person who genuinely cares," he continued.

"And although what’s happened in the past has happened, I just want to make the best impression on people and be kind and loving and gentle and soft. And although people can call me a 'softy,' that’s how my mom raised me."
