Kathryn C. Dennis Gushes That She "Gained a Sister" at Her Brother Luke Dennis' Fairytale Wedding

The Dennis family had a lot to celebrate this weekend. Kathryn C. Dennis' older brother, Luke Dennis, tied the knot with his fiancée, Natalie Verenes, in Columbia, South Carolina on Saturday, December 8. 

Kathryn reflected on her big brother's major milestone prior to the ceremony on Saturday. "Many men can make a fortune. But very few can build a family," she shared on Instagram in a post that featured a photo of herself and her 4-year-old daughter, Kensie, wearing some extra pretty outfits. "CanNOT believe my big brother Luke is getting married tomorrow. Just yesterday we were 2 [hot] redheaded noodles running around and now we're making our own families. #stillgoingtocallyouLukieDukie."

Luke and Natalie first met while working for South Carolina state senator Glenn McConnell when they were students at USC in 2012, according to their wedding's page on The Knot. Their friendship eventually turned romantic, and on April 29, 2017, Luke proposed to Natalie on the grounds of the State House where they first met. "The State House will always have special meaning to us. It was only fitting that we returned to this beautiful, historic place to have our engagement pictures taken," Natalie shared on The Knot, adding that their wedding "will be the culmination of six years of a wonderful journey."

Not only did Kensie and her 3-year-old brother, Saint Julien, get to watch their uncle Luke say "I do" at the Millstone at Adams Pond in Columbia, but Kathryn's children also got to be a part of a wedding for the very first time. Kensie and Saint served as flower girl and ring-bearer during the ceremony, respectively. Kathryn and Luke's father, Luke Dennis Sr., also served as best man in the wedding. "Once in a while, right in the middle of an ordinary life, love gives us a fairytale," Kathryn gushed on Instagram in a post featuring photos of her kids looking absolutely adorable at the nuptials.

Once the ceremony was over, it was time to party. Everyone took to the dance floor, including Kensie and Saint, who couldn't get enough of the glow stick necklaces. And who could blame them, really?

It sounds like Kathryn couldn't be happier to have a new member of the family in Natalie. "I gained a sister yesterday," Kathryn shared on Instagram in a post that featured photos of herself with the bride and groom. "Welcome to our family, Natalie."
