Jana Kramer Says 'There's a Lot of Things I Regret Saying' Following Mike Caussin Split Last week, Kramer also tweeted, "And the lies keep on comin. I feel a country song brewin," seemingly referring to her divorcee. Kramer — who hosts iHeartRadio's Whine Down podcast — finalized her divorce from Caussin late last month. (The couple had been married for six years and share son Jace Joseph, 2½, and daughter Jolie Rae, 5.) "Today has not been easy and I didn't know if I would even say anything. If I'm honest I had no idea how I would feel. Relieved? Sad? But I got the 'final' call that I'm officially divorced and the tears came," she wrote on Instagram at the time. "My first feeling was failure. That I failed my kids. That I was unlovable, not enough. I had moments of anger that I never wanted this for my reality, for my kids." She continued, "Let's just say it was all the feels but here's what I know….I didn't fail my kids. I'm showing them a strong momma and I'll continue to do that and walk away knowing I did everything I could. This isn't the end…it's just the beginning of my story and I'm excited, hopeful, and ready to continue the healing so I can be stronger, and love deeper."

At the time, Kramer shared a lengthy post addressing her decision. "I just can't fight any longer. It's time to heal," Kramer continued. "Thank you for all the love, heart, and support, in many ways you have fought on this journey alongside me, and for that I am grateful." In court docs, the One Tree Hill alum cited "inappropriate marital conduct, irreconcilable differences and adultery" as grounds for her divorce from Caussin.
