What Caused Herjavec and Diane Plese’s Divorce?

Like any couple, Diane Plese and Robert Herjavec had numerous issues in their 25 years together. But none of these issues could make them think of divorcing for that long. That’s one of the reasons why many admire the couple for staying together for a long time. Many had assumed they would always be together.

On July 25, 2014, Diane and Robert announced their separation. Robert had cheated on Diane, triggering her to sue for separation. But even as they separated, Diane said that despite Robert being a loving and caring person, she didn’t want to live with him anymore. In March 2015, Diane filed for divorce.

It was a difficult moment for Herjavec. He felt humiliated by Plese’s decision to divorce him and said he would have wished for the family to stay intact. But he had no other option in this. At the risk of sounding overly wise and in retrospect, he observed how difficult it was for human relationships to work seamlessly. He said he wished his family would enjoy peaceful coexistence amid the divorce.

At the time of announcing the divorce, none of the two was willing to reveal the actual trigger of the move. However, as divorce proceedings progressed in court, it emerged that Robert had cheated on Diane with Danielle Vasinova, an actress, in 2014. Robert had tried everything to hide the relationship from Diane. But his efforts were futile since Diane eventually learned about it. And she couldn’t come to terms with it. As soon as Diane learned of the affair, she made up her mind to separate from Robert.

Please eventually sue to divorce Herjavec. During the divorce proceedings, she did everything in her power to leave the marriage with a substantial fortune. She wanted, as much as she could, to squeeze the last coin from her ex-husband. But Robert could hear none of that. Hence, he contested Diane’s demands, leading to an acrimonious divorce.

How Long Did the Divorce Battle Stretch Out?

According to media reports, it would have been easier for Diane Plese and her ex-husband arrive at a workable divorce settlement if they had a prenuptial agreement. Unfortunately, the two had no such arrangement before entering the marriage.

As a result, they had long-drawn divorce proceedings due to disagreements concerning finances. For once, they couldn’t agree on Herjavec’s true net worth and the actual value of the property and houses they owned. In fact, Plese had to go back to court for an additional settlement long after the a court had settled the matter the first time.

In 1996, Herjavec had established a trust fund. The first major investment was worth $21 million in 2000. Over the years, he had withdrawn money from the fund to pay his children’s tuition fees and other family expenses. By 2014, when Diane filed for divorce, the trust was virtually depleted. In order to have her ex-husband found in violation of trust, she requested that the court do so. She requested that the court compel Herjavec to restore the trust.

However, the court couldn’t agree with her. After protracted proceedings that lasted until 2016, the court ordered Herjavec to pay $167,000 monthly as spousal and child support. The court also ordered that she be paid $25 after the sale of some family assets.

Diane Plese wasn’t satisfied with what seemed as the conclusion of their divorce. She still believed that Herjavec had understated his net worth. So, she teamed up with Danielle Vasinova, her ex-husband’s former mistress. Herjavec had confided in Vasinova about his decision to undervalue his assets by more than half. 

Now, Vasinova was willing to testify in court in favor of Diane’s case. Thus, Plese amended the divorce pleadings to include Vasinova as a witness. In 2019, she got an additional $2.6 million award as an equalization payment. She also got $2.8 million, being proceeds of the sale of the family properties in Florida and Caledon.

Did Diane Plese Remarry? What About Her Ex-Husband?

Diane Plese has never remarried after the divorce. She remains single and has chosen to stay out of the limelight. However, due to her obscure life, it’s difficult to tell what exactly she’s up to. With a $25 million settlement from the divorce and three children to take care of, she should have her hands full. 

But that cannot be said about Herjavec, who has since moved on and started another relationship. Soon after the divorce, Robert couldn’t imagine living without his family. At some point, he contemplated taking his own life. Diane had left with the children, who no longer wanted anything to do with him. 

So, Herjavec is in a relationship with Kym Johnson, an Australian pro dancer. It seemed he couldn’t wait to start a new relationship, hooking up with Kym in July 2016. They met Dancing with the Stars in 2015 and soon developed an interest in each other. The couple has twins, Hudson and Haven, born in April 2018.

Kym, Herjavec’s latest wife is an actress, book author, and TV host. The couple lives with their two children in Hidden Hills, where they have a home. It seems that, between the two, Robert has reservations about having more children. But who knows what the future holds?

Unconfirmed media reports indicated that Herjavec had, in mid-2017, sued an ex-girlfriend for extorting money from him. The ex-girlfriend filed a counter-claim, accusing Herjavec of sexual assault. Although no details have emerged from the cases, the suits were dismissed without financial settlement.

Diane Plese had three children with Robert Herjavec throughout their 25 years of marriage. The first is her son Brendan, followed by daughters Skye and Caprice. When their divorce was concluded in 2016, the children were teenagers. So, they had issues with their father for causing the divorce by being unfaithful to their mother.
