Kristin Cavallari and estranged husband Jay Cutler were plagued by cheating rumors

Kristin Cavallari claimed her estranged husband Jay Cutler is ‘guilty of ‘marital misconduct’ in divorce documents she filed on Friday.

The divorce filings comes amid cheating rumors that have plagued the couple of more than 10 years.  

During the last season of their reality show Very Cavallari, Kristin and her former best friend Kelly Henderson had a falling out after speculation that she and Jay were allegedly having an affair.

The former MTV reality star said she didn’t believe the affair accusations ‘not for one second’, but was opposed to how Kelly reacted to it.

Kristin believed the Velvet’s Edge blogger added ‘fuel to the fire’ by bringing up Jay on Twitter and felt she ‘was using Jay for her own personal gain.’

‘If I was accused of having an affair with your husband, I wouldn’t say his f***ing name on social media. Like, come on,’ Kristin complained to friends Justin Anderson and Stephanie ‘Biegs’ Biegel on the show.

Kristin had said on the show: ‘Instead of her just owning her side of it and being like, “I’m sorry! Oh my God, that was never my intention,” or whatever, she kept giving me push back and would get really defensive. And then she literally stopped responding to me.’

Kristin spoke out about her falling out with her best friend and how her reaction to it hurt her in the season premiere of the show. 

The reality star also talked to Jay during the season three premiere titled Uncommon Beginnings after not speaking with Kelly for months.

Kristin earlier revealed on her E! show that her relationship with Kelly had ‘completely taken a turn’ after she was accused of having an affair last season with Jay on social media.

‘The biggest change in my personal life is that my best friend Kelly and I haven’t talked in two months,’ Kristin said in a confessional. ‘We’ve had a major falling out and it’s just been breaking my heart.’

Kristin was feeling ’emotionally drained’ by the falling out and also talked to Jay about it during the show.

‘Like, my best friend could care less about me, unless it has to do with what she can gain from me and you,’ she told the former NFL quarterback.

In addition, the star claimed that Kelly ‘never once’ said sorry over the escalation of the situation with the last interaction an olive branch from Kristin to her.

Kristin says she had written to Kelly: ‘I miss you and this has been absolutely killing me. I’m sorry, I know I’m tough when I’m hurt. I love you and we need to fix this.’

After Kelly never responded, Kristin had said it was ‘the final straw in their friendship.’

During an episode earlier this month, Kristin talked about the ‘ups and downs’ of their marriage.

She had said: ‘Jay has been great, yes. From the outside, things are so perfect and things are so great. But actually, they’re not. And that sucks. Its sucks. That’s the thing, though, with marriage… it’s ups and downs.’

Kristin has alleged ‘misconduct’ by estranged husband Jay in the legal documents, according to TMZ.

The 33-year-old reality star and fashion designer, who shares three kids with the 36-year-old former football player, had claimed in the documents that Jay is ‘guilty of such inappropriate marital conduct as renders further cohabitation unsafe and improper.’

In addition, Kristin claims in the filing that Jay insinuated misconduct on her part; the document says: ‘Any misconduct alleged or implied against her in the complaint for divorce was in response to and/or as a result of misconduct on behalf of her Husband,’ via the outlet. 

Kristin and Jay both filed on Friday, two days before she announced their split on Instagram, according to US Weekly. 

Her date of separation, April 7, interestingly enough is the day she and Jay got back to Nashville after they were stuck in the Bahamas for three weeks, Us Weekly reported.   

Jay didn’t note any ‘misconduct’ in his divorce filings and listed their separation date as April 21. 

Kristin, who became a household name on MTV reality shows Laguna Beach and The Hills, wants primary physical custody of their three kids, child support, and for Jay to pay for their health insurance.

Meanwhile Jay is requesting joint custody of their children.

They are parents to sons Camden, seven, Jaxon, five, and daughter Saylor, four. 

She claimed that Jay wasn’t available as a father to their kids in her filing, which he denied in his filing.

Kristin had in her filing: ‘She denies that Husband has always been the available at home parent and primary caretaker of the parties’ minor children. Wife would show that she had been the primary residential parent.’

Jay said in his filing: ‘Husband has always been the available at-home parent and the primary caretaker of the parties minor children. 

She is also asking for Jay to maintain a life insurance policy with her listed as the sole beneficiary.

On Sunday, Kristin shared an image of her and Jay walking with their arms around each other; In the caption, she announced their split, writing: ‘With great sadness, after 10 years together we have come to a loving conclusion to get a divorce.’

Adding: ‘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. We ask everyone to respect or privacy as we navigate this difficult time within our family.’ 

Their split came after they returned to the states following trip to Bahamas that sparked backlash due to the COVID-19 pandemic.

They went on holiday with their three kids, her hair stylist pal Justin Anderson and his fiance Austin ‘Scoot’ Rhodes. 

They weren’t able to fly back and ended up staying three weeks. 

However, the duo already planned on splitting prior to their trip, according to People.

‘On their recent trip, they already knew they were splitting up. Kristin and Jay had been having problems for a long time. They hadn’t spent much time together in recent months.’

People’s source claimed that Kristin’s busy career and differing priorities led to their split: ‘Kristin and Jay are a lot different. She has so much on her plate, with her brands and with her show, and Jay is not as interested in all of that. She’s so passionate about her work and they couldn’t relate to each other. So it pulled them apart.’  

They met in 2010 and dated for 10 months before he proposed to her in April 2011; they called off their engagement in July but reunited by December of that same year.

They tied the knot on June 8, 2013 in Nashville, Tennessee.
