"Jon basically lives his life and I live mine... it's more peaceful and it's probably not anything I'm doing differently," she told Dr. Drew.
Gosselin, whose reality show, “Kate Plus 8,” ended in September 2011, said their improved relationship might have something to do with her ex-husband's recent employment.
"He feels like he's living a regular life again and maybe [he's] a little happier himself, so that boils down to peace between us. The kids are now okay going there," the reality TV star said. "I feel like he's trying again. The bottom line is, the kids come home happy, basically, so that's all that matters."
Her sentiments are a departure from earlier comments she made about their acrimonious split; in December 2010, Gosselin told "Today Show" co-host Meredith Vieira that she hadn't yet made up with Jon after their highly publicized split, and that two of their children, Collin and Alexis, had anger issues, which she believed stemmed from the couple's divorce.
Gosselin filed for divorce from Jon in June 2009 after ten years of marriage, amid rumors of Jon's infidelity.
