More than four years after they started dating the couple exchanged vows in a private ceremony at their home in Los Angeles.Christina and Martyn welcomed daughter Sadie back in January of 2011. In the past the Anchorman actress has credited Martyn for helping her get through her battle with breast cancer. We couldn't be happier for Christina! Congrats to the happy couple.
