Kat Graham, 34, and Bryant Wood, 29, tied the knot in a secret legal ceremony officiated by a friend in Los Angeles.
The couple, who had been best friends for five years, chose matching white outfits for their intimate wedding.
Bryant, a breathwork instructor and co-founder of the wellness company Modern Nirvana, is also an actor, with appearances on shows like The Circle and America's Next Top Model.
Their romance blossomed in June, following Kat's breakup from her former fiancé, Darren Genet, whom she had been with for six years.
Kat announced her split from Darren on Instagram, expressing good wishes for his future and emphasizing the amicable nature of their separation.
This marks Kat Graham's second engagement, having previously been engaged to actor Cottrell Guidry before their 2014 split.
