The country star, 27, and her hockey player beau, 30, tied the knot at the Ritz Carlton Reynolds Plantation in Georgia Saturday before 250 friends and family in a ceremony featuring classical music and the couple's favorite Bible readings.
“We could not feel more blessed to have found each other and to have shared this day with our friends and family that mean so much to us!” the newlyweds told PEOPLE in a statement, signing their names “Mike & Carrie Fisher.”
Underwood wore a Chantilly lace dress created for her by Monique Lhuillier, who also designed the bridesmaids’ dresses.
Fisher, who plays for the Ottawa Senators, was engaged to Underwood on Dec. 20, after quietly dating for about a year. Underwood told PEOPLE in March that with their busy schedules, “We'll be little nomads for a while” and that they planned to keep homes in Nashville and in Peterborough, Ontario.
