Two days before the concert, Bronson and fellow Zumba instructor Korinn Scattoloni of Camden were given choreography to learn.
"It's one of those repetitious Zumba songs that's really fun," she said.
And when Bronson showed up hours before the show to practice the routine on stage, she got to meet Victoria Justice in person.
"It was just for a second when I first walked on stage for the sound check. She said, 'Hi' and 'Thank you for being here,'" Bronson said.
Zumba also made sure Bronson and Scattoloni were all decked out in Zumba apparel for the big performance.
"They sent us a tank top, sports bra, sweat bands, pants and sneakers to wear, and they paid us too," she said.
Bronson said it's an experience she and her young niece Lily will never forget.
"There were a lot of lights and smoke machines. My niece was excited to be there in the audience and say she could see her aunt on stage," Bronson said. "It was so much fun. I'd do it again in an heartbeat."
