"Yes, Mike and Carrie are married," Underwood's publicist Jessie Schmidt said in an e-mail to The Associated Press early Sunday.
The wedding took place Saturday at the Reynolds Plantation resort in Greensboro.
The 27-year-old winner of the fourth season of "American Idol" and her hockey player beau, 30, said "I do" at the luxury resort before 250 guests, People.com reports.
"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 couple told People in a statement.
Underwood's Chantilly lace dress was by Monique Lhuillier, who also designed the bridesmaids' outfits, according to People.com.
