Fishel, 32, wed boyfriend Tim Belusko, 25, in a short ceremony in downtown Los Angeles. The actress wore a strapless lace Enzoani gown and walked down the aisle to the song "Forever" by Brian Culbertson. The affair had more than 200 guests including costar Ben Savage.
The couple met in school where Fishel was returning at the age of 27 to get her college degree. She graduated in December 2012.
"I persevered and sometimes I wasn't the oldest person in class, some of the whisperers became good friends, and I did so well in math, I even became a tutor. And that is how I met my fiancé. :)" she wrote on her Tumblr when she graduated.
Fishel, who grew up on television playing Topanga Lawrence on the ABC sitcom, is reprising her role on the upcoming Disney spin-off Girl Meets World. Fellow Boy Meets World alum Rider Strong also reportedly got married this weekend.
