Kristin married former Chicago Bears quarterback, Jay Cutler, in 2015. However, five years later in 2020, the two decided to split and file for divorce. 

Due to financial situations, the process of divorcing was put on pause in 2021. As of June 2022, the two have officially been divorced after reaching a settlement. They will still co-parent their three kids. 

A source stated to Us Weekly at the time of the divorce that the two exes, 'fell out of love and grew apart.'  

According to the publication, Jay stated on his podcast called Uncut, that, 'When the settlement came through, I threw a party.' He added in explanation that, 'I don’t recommend divorce for anybody,' but that it was the best for Kristen and himself.
