Ferrera and Williams were married on Monday night in a ceremony attended by Vanessa Williams and Rebecca Romjin, who are former co-stars from the ABC comedy, said the actress' spokeswoman Carrie Byalick.
"Ugly Betty" ran from 2006 to 2010, and since then the 27 year-old Ferrera has played a recurring role on CBS drama "The Good Wife."
Williams is a filmmaker who directed "The Dry Land," an independent film released last year that starred Ferrera.
Ferrera won an Emmy, a Golden Globe for her remarkable performance as Betty Saurez on "Ugly Betty".
The couple first met at the University of South California and Williams cast her in his student film. They became engaged last year.
