Levy herself shared a snap from a photo booth session with her new husband on Instagram.
"Bells are ringing," she wrote. "10.16.2021."
Earlier this year, Dan Levy shared a snap of his sister wearing a sash featuring photos of herself with her fiance ahead of the big day, sitting beside cupcakes and a balloon reading "Happily Ever After".
"Sister getting married!" Dan Levy wrote alongside the post. "Let's go @sarahplevy."
The couple have been together since at least 2018.
When Schitt's Creek ended in April 2020 after six seasons, Outerbridge raved about his now-wife's starring role on the series as Twyla.
"Words can't describe how proud I am of this wonderful woman," he wrote on Instagram alongside a photo of her in character. "She's the most talented and graceful person I've met, and I'm luckier than I could ever imagine! I love you @sarahplevy! Twyla was such a gift!"
Last month he marked her 35th birthday with a sweet social media tribute.
"I have 22 minutes to post this, but I could not be happier to spend Sept. 10th with this stunning birthday girl," he wrote alongside a candid snap of the couple.
"I love you @sarahplevy," he continued. Have a wonderful Birthday. This photo is soy candid."
Levy celebrated her Outerbridge's birthday earlier this year.
"Another year around the sun and what a year it's been," she wrote in August. "Happiest birthday @instagraham_sto love you so much."
