After more than eight years together, Harrison Ford and Calista Flockhart have tied the knot, their reps confirm to PEOPLE.
Ford surprised Flockhart with a Valentine’s Day wedding proposal in 2009. They were married Tuesday in New Mexico, where the actor is filming Cowboys and Aliens.
The wedding, which took place at the Governor’s Mansion in Santa Fe, was performed by Governor Bill Richardson under the legal supervision of New Mexico’s Chief Justice, Charles W. Daniels, who officially declared the couple legally wed.
Gov. Richardson and his wife, Barbara, who are friends of the couple, were witnesses for the bride and groom. The couple’s son Liam, 9, was also in attendance, as was the governor’s official counsel.
The mansion sits atop a hill north of downtown Santa Fe.
