I'm always on time or early and she's always late, so I'll be waiting for her in the heat or something."

Adds the Golden Buzzer recipient, "All the judges are super nice and I have received a lot of great advice, especially from Howie [Mandel]. Tyra [Banks] is very supportive and caring. She helped calm my nerves and regain confidence just before my first live performance."
