Here are three things we bet you didn't know about the 33-year-old Florida native.
1. Her nickname growing up was Gabby Abby.
"My brothers started it, and I hated it," Spencer tells PEOPLE. "I was a pretty incessant talker as a child, and I had a really loud voice. Now I have a son [Roman, 6] who does the same thing, and I'm just like, 'Oh my gosh!' "
2. Her biggest fear is tornadoes.
"I am terrified at the possibility," admits the actress. "If a dark cloud gets a little spiral-y I'm like, 'It's a twister!' I think I have Wizard of Oz syndrome. Ever since I saw that movie – the nightmares! I actually had been in Oklahoma during a tornado, and I will say it was terrifying. I just shut down completely. I just did not know what to do with myself."

3. She's been surfing since she was 3."I started surfing when I was 3, but that does not mean that I'm great at it by any means – it just means I've been doing it a long time," says Spencer. "My dad was a professional surfer, so he introduced me to the sport at a very young age."
