The Addams Family star married fiancé James Heerdegen at a private ceremony in New York City on Saturday (26 October) and, despite keeping their nuptials away from the public eye, she couldn't resist sharing a photo of herself looking stunning on the big day.
Christina wore an ethereal looking white Givenchy haute couture gown designed by Riccardo Tisci. She tweeted alongside her gorgeous pictures: "I'm sorry I have to share what @riccardotisci made for me!! #iloveyouricky!"
Elegant, sophisticated and eternally beautiful.
Christina met James, a camera technician, on the set of her TV series Pan Am, which aired in 2011. They announced their engagement in February 2012.
At the time, Christina told People magazine she couldn't wait to be a bride, joking: "I can't wait for 'husband' because then I can really throw my weight around. 'My husband's going to come down here and talk to you!' That's a huge threat."
Christina, 33, rose to fame as a child star in films like The Addams Family, Casper and Now And Then. Her more recent films have included Bel Ami and The Smurfs 2.
