"I'm married to my best friend!" Lambert, a former "Nashville Star" finalist, told Us afterward. "Looking forward to a lifetime of laughter."
Shelton, who currently serves as a coach on NBC's new "The Voice" singing competition, kicked in by saying he'd been waiting for this day since he proposed a year ago.
"I wanted to be married to Miranda the day I proposed," he said. "Finally, it's official!"
It's the first marriage for the 27-year-old Lambert and second for the 34-year-old Shelton, who was married to Kaynette Williams from 2003 to 2006.
Lambert is known such songs as "House That Built Me" and her albums "Kerosene," "Crazy Ex-Girlfriend" and "Revolution."
Shelton has five albums under his belt and eight No. 1 hits, including this year's "Who Are You When I'm Not Looking."
