Jana Kramer “lost almost half” of her money in her divorce.

The country singer and former One Tree Hill star regrets not having a prenuptial agreement in place when she married Mike Caussin — with whom she has daughter Jolie, 8, and five-year-old son Jace — in May 2015, because her assets weren’t protected, even though she belatedly made him sign a postnuptial contract when it emerged that he had been unfaithful.

Speaking on I Do, Part 2 with Jennie Garth, Amy Robach and T.J. Holmes, Kramer said, “In my last marriage, to my husband of almost seven years, I did not have him sign a prenup.

“To me it was, ‘This is my one, forever, and we’re getting married.’ When he cheated, the first round of affairs when he was in rehab, I made him sign a postnup. But that did not hold up in court,” she explained.

The couple split in 2021, and the 40-year-old star’s lawyer warned her that postnuptial agreements “don’t hold up as well” as those signed before marriage, so she made a spreadsheet setting out what she felt was fair, but the 37-year-old former footballer was ready to fight it.

Kramer — who noted that she pays Caussin child support — said, “I earned most of the money in that relationship.”

Kramer married again in July, but before she and Allan Russell — with whom she has 10-month-old son Roman — tied the knot, her lawyers sat her down to talk about a prenup and described it as like “getting health insurance,” but she still found it a “really hard conversation to have.”

“He’s the love of my life, and I don’t want to have a prenup. Having said that, I look at the other side and I realize I lost almost half of my money in my last divorce. Money that I worked really hard for,” she stated.

When she spoke to Allan about it, he said, “I will sign it if you want me to sign it.”

“I’m not gonna actually say what the end decision was, but for me, it was a really tough conversation to have,” she added.
