JB Gaynor was born in Harbor City, California, to John and Mary Gaynor.
JB is in elementary school, his favorite subject is math. JB decided to
pursue an acting career growing up watching his sister, Jennifer. Jim
Carrey and John Travolta have influenced the young star. JB would like
to be a basketball player or a veterinarian.
I actually remember when I first wanted to be an actor. I was watching TV and I saw my sister and I said, "I want to do the same thing that she does". So my mom put me in and I've been doing it since I was like four.
