Jana Kramer "lost almost half" her money in her divorce.

The 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 he had been unfaithful.

Speaking on I Do, Part 2 with Jennie Garth, Amy Robach and T.J. Holmes, Jenna 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.

Jenna - who noted she pays Mike child support - said: "I earned most of the money in that relationship."

The Why Ya Wanna singer married for a second time 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 Jenna 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," Jana 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.
