The 'Since U Been Gone' hitmaker tied the knot with Brandon Blackstock on Sunday at Blackberry Farm in Walland, Tennessee and took to Twitter the following day to confirm news, reported Us magazine.
The 31-year-old singer returned to the microblogging site to share a professionally-filmed video, which captures moments from the newlyweds' big day, and wrote, "Here is a little video of our special day! Thanks to everyone for all of your well wishes."
The clips of Clarkson and her groom were backed by Patti Griffin's ballad Heavenly Day.
The small affair was only attended by Blackstock's son and daughter from his previous marriage. They served as the maid of honour and best man at the ceremony.
