The "Dancing With The Stars" judge married Brooks on Saturday in a ceremony in Idaho, reported People.
"I don't think I ever really necessarily dreamed about my wedding as a kid. But I know I will always cherish and remember it for the rest of my life," Julianne said.
The 29-year-old star wore a custom-made Marchesa dress and jewels from Lorraine, while her groom wore a tuxedo from Brooks Brothers.
The couple tied the knot in an outdoor ceremony in front of 200 friends and family members, along with their two Cavalier King Charles Spaniels, Lexi and Harley, who served as ring bearers.
Guests included Julianne's brother Derek Hough, who served as groomsman, Aaron Paul, Mark Ballas and actress Nina Dobrev.
Julianne and Brooks got engaged in August 2015.
