This is going to be an extra-special Christmas for Gwen and her husband Blake Shelton, as it's their first as a married couple.
They tied the knot in the summer in an intimate ceremony held at their ranch in Oklahoma. The wedding was attended by their family and close friends, including The Voice host Carson Daly, who officiated their big day.
