She was married to Cutler, former quarterback for the Chicago Bears, from 2013 until they split in April 2020, with their divorce finalized in June 2022.

In a 2022 interview with Call Her Daddy, Kristin described her relationship with Cutler as ‘toxic.’

She told host Alex Cooper that she was ‘really unhappy’ and in an ‘unhealthy relationship’ and didn’t want her kids to think that ‘was normal.’

Kristin said that ending their marriage was ‘really scary’ and a decision that took her ‘a few years to to actually pull the trigger.’

‘It was just time. Nothing major happened. At the end, it was just time.. It’s the scariest thing. It’s always the saddest thing. I mean, it’s so many emotions, but it can also be the best thing.’

She said she doesn’t regret anything and is ‘thankful’ for their time together because of their three children.

After the split, Kristin put herself back in the dating game.

She was linked to standup comedian Jeff Dye, 41, for five months before calling it quits in May 2021.

His attempt to rekindle things last October went terribly wrong as Dye, who is now sober, was arrested for DUI after he crashed his car into a tree on the way to meet Kristin for coffee in Los Angeles.

Kristin’ most recent fling was with The Bachelorette alum Tyler Cameron, 31.
