Yes, Karla Mosley (think I spelled that right).....she was on the kids' show "Hi 5" for many years. My girls always loved watching that when growing up, and truth be told, my younger one (age 9) still will watch it if she finds it on tv.....LOL!! My girls always got a kick out of the actors/actresses on that show, and immediately recognized Karla when they saw her on GL when I was watching it.
It's just a fun, silly show with young actors/actresses to entertain the little ones......music, dancing, whatever.
I think I recall reading an interview with her where she mentioned it was filmed in Australia......cool!
She was on that show long before she got her GL part.
