Cavallari filed for divorce from Cutler in April 2020 after seven years of marriage. The couple share three children: Camden, 11, Jaxon,9, and Saylor, 7. 

"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. This is just the situation of two people growing apart," the couple said in a joint Instagram statement at the time.

Now, Cavallari is focusing her new relationship with Mark Estes, a member of the TikTok group Montana Boyz. 

When speaking with "Entertainment Tonight" on the CMT Music Awards red carpet in April, Estes got candid about his budding romance with Cavallari.
