It seems Kristin Cavallari and Jay Cutler may be friendly exes after all.

The pair announced their split in April and since then rumors of both contention and cordiality have surrounded them both.

On Father's Day, however, Cavallari, 33, put any ill feelings she may have away to celebrate Cutler, 37, with their three little ones: Camden, 7, Jaxon, 6, and Saylor, 4.

"Saved the best for last....happy (late) Father’s Day to Jay. We had a beautiful day together yesterday at my new house," Cavallari wrote in the caption. "Modern family? Co-parenting? Whatever you want to call it, we are navigating it the best way we know how. And what I do know is, our 3 kids are lucky to have him as their daddy."
