"With great sadness, after 10 years together we have come to a loving conclusion to get a divorce," the 33-year-old reality star wrote on Instagram Sunday. "We have nothing but love and respect for one another and are deeply grateful for the years shared, memories made, and the children we are so proud of."
The couple married on June 8, 2013, in Nashville, Tennessee. They have two sons, Camden, 7, and Jaxon, 5, and a daughter, Saylor, 4.
"This is just the situation of two people growing apart," Cavallari continued in her post. "We ask everyone to respect our privacy as we navigate this difficult time within our family."
