On Sunday, May 9, the retired NFL star posted on his Instagram page a photo of Kristin playing on the grass with their sons Camden Jack, 8, and Jaxon Wyatt, 7, and daughter Saylor James, 5.
"Some kids have all the luck," Jay wrote. "Happy Mother's Day @kristincavallari."
He has paid tribute to Kristin online since their breakup before. Last Mother's Day, just two weeks after their breakup announcement, he honored her with an Instagram pic of her with their kids, writing, "Happy Mother's day to all the moms. These 3 little ones picked a good one." He later deleted the post.
Since their breakup, Jay has also occasionally promoted Kristin's 2020 cookbook, True Comfort: More Than 100 Cozy Recipes Free of Gluten and Refined Sugar, including in February before the 2021 Super Bowl.
