Three years after Jon Gosselin, 35, and Kate Gosselin's public and heated divorce, Jon is finally extending an olive branch to his ex-wife and the mother of his eight children — sextuplets and a set of twin girls — and the star of the former TLC series, Jon & Kate Plus 8, which morphed into Kate Plus 8 after their split.

"I am sorry, because I did stuff I wouldn't want done to me," Gosselin told People. "I was passive-aggressive. Then I'd get mad, but I was the one who wasn't communicating," he acknowledged. Around the time of Jon's split with Kate, he was going out, partying a lot, and openly dating a string of younger women.

But now he claims he has calmed down and that he manages to maintain a healthy friendship with Kate, 37. "I'll call [Kate] up and say, 'Mady's sick. What do I do?' And she'll tell me. She's a great mom. We just have different parenting styles."

Gosselin's newfound sense of calm is partly due to his conversations with Rabbi Shmuley Boteach, who also counseled Michael Jackson when he was alive. "There are two things you can do with your fame," the Rabbi told Gosselin. "Sell it out or take it and use it for good. I didn't grasp that at the time."
