“It’s one of those things that we’re just handling privately,” Kate said on Wednesday’s taping of The Rachael Ray Show. “We’re just taking it one step at a time and I’m trying to walk through it.”

She added: “The focus remains on our kids. It has always been there and will continue to be there. One day at a time, like we’ve always done. One hour at a time, one minute at a time, and my life’s been like that.”

Her interview with Rachael Ray — which will air on Tuesday — came the same day Us Weekly’s current issue (on newsstands now) revealed that five people close to the situation confirmed that Jon, 32, has been having an affair with third-grade school teacher Deanna Hummel.
