"Mrs. Carol Denise Betts [ring emoji] @jessicabettsmusic #LoveWins [rainbow emoji]," Nash, whose real name is Carol Denise Nash, captioned a photo of the happy couple on their wedding day.
Even though the wedding came as a surprise to fans, the couple knew each other for years.
Back in 2016, Betts posted a video of Nash praising her work as a musician. They also spent time together while on the set of "Claws" in 2018. In February 2020, Betts posted a photo of Nash in honor of the "Scream Queens" alum's 50th birthday.
Speaking to People, Nash said that her wedding "has absolutely nothing to do with gender and it has everything to do with her soul."
"I was not suppressing my sexuality my whole life," she said. "I love who I love."
Nash added: "I don't feel like my marriage is my coming out of anywhere, but rather a going into myself and being honest about who I love. And I'm not limiting myself on what that love is supposed to look like."
Nash's first wedding was to Don Nash in 1994. The couple split in 2007. She went on to marry Jay Tucker in 2011, but filed for divorce in 2019.
The actress told People that after her split with Tucker, she and Betts became closer.
"We began to see each other in a way we never had before," she said. "Sometimes you get so broken by love, you run from it. But I've learned that you should always hold space for magic because it can happen at any time."
