The actress wed actor Dave Abrams on Saturday night, they told People magazine.
"It was the perfect night," they said. "We are so happy to have our family and friends surrounding us on this special occasion!"
Garth, 43, and Abrams, 34, met last year and announced their engagement in April. Two months later, the former "90210" star told ABC News that she was planning the nuptials on her own.
"I want people to be comfortable. That's my priority," she told ABC News. "No uncomfortable clothing. No high heels!"
