"It's our light at the end of the tunnel," the 29-year-old "Fastest Girl in Town" singer says in the Dec. 3 issue of Us Weekly (out now). "We can stop rushing around and just be together."
So when her Voice mentor hubby, 36, asked her to duet on "Home" for his NBC special, Blake Shelton's Not So Family Christmas, Lambert was happy to oblige. "It's Blake's dream to host a holiday show," she explains. "I'm glad to be a part of it. I loved watching him sing with Reba McEntire and Kelly Clarkson. He was so comfortable with the biggest divas on the planet!"
The holidays have always been important to the "Honey Bee" singer, according to Lambert. Just like his mother, Dorothy Shackleford, Shelton loves "to decorate the house" for Christmas. "Blake likes to pick food out of a magazine for me to make. Last year it was gourmet mac 'n' cheese. It took me three hours!"
With 16 successful months of marriage under her belt, Lambert is eager to spend the season with the man she loves most. "We just have fun together," she tells Us. "I thick romance and love stories are great, but at the end of the day, you've got to be friends."
Blake Shelton's Not So Family Christmas airs Monday, Dec. 3, at 10 p.m. on NBC.
