The couple walked down the aisle this weekend in a private ceremony that took place in Italy.
“We are happy to confirm that Maggie and Peter were married on Saturday,” their reps told E! News.
This is the first marriage for both the 31-year-old Dark Knight-starring Gyllenhaal and her 38-year-old beau, whose credits include a Golden Globe-nominated turn in Shattered Glass (and one hysterical SNL skit).
The über-private couple have been together since 2002 and engaged since 2006. In October 2006, Gyllenhaal and Sarsgaard became first-time parents to daughter Ramona, now 2.
