Johnson, a retired Olympic gymnast, wed NFL player Andrew East in a barn-chic ceremony on Saturday in Tennessee, E! News reported.
The bride, 24, reportedly donned a custom-made, strapless, lace embroidered Olia Zavozina wedding gown with a mermaid skirt and long train. The ivory dress was capped off with a cathedral-length veil, and the gold medalist carried a bouquet of white flowers down the aisle which was adorned on both sides with metal lanterns topped with white flowers.
As for the groom, he sported a black tux, brown shoes, ivory tie and white boutonniere.
The couple had nine bridesmaids and groomsmen in their wedding, according to E! News, and they exchanged vows on a grassy knoll near a barn in front of at least 150 family members and friends.
Johnson and East got engaged in July 2015. He popped the question at a Chicago Cubs baseball game right on the field.
In May 2009, Johnson won Dancing with the Stars' eighth season with pro partner Mark Ballas. She returned to compete on the ABC reality dancing competition's all-stars edition in November 2012, placing second with pro partner Derek Hough.
