The breakdown of their marriage played out as viewers watched on "Jon and Kate Plus 8," but now, long after the divorce (and the series end), the animosity between Jon and Kate Gosselin continues.
In fact, it seems to be at an all-time high, now that the parents of both twins and sextuplets are headed to court.
In the latest legal struggle between the exes, Kate has filed suit, accusing her ex of hacking her phone and computer, and even stealing a hard drive, in order to gain allegedly defamatory material for Robert Hoffman's tell-all tome, "Kate Gosselin: How She Fooled the World."
Kate visited TODAY Tuesday morning to explain why she felt the lawsuit was necessary.
"It's in the middle of litigation, so I cannot say a lot about it," she warned before continuing. "I can say that when we started out investigating the source of what was happening, I made the decision back then to push this. … Actually, I've lost a lot of employment opportunities over the rumor mill circulating false stuff."
She added that "the most unexpected and disappointing" part of it all was learning "who was at the center of it." And although she believes that to be the father of her children, who can be seen in the video during an alleged run-in with a paparazzo, she doesn't regret taking legal action.
"It has to be done for the safety and the future of my kids," she told TODAY's Savannah Guthrie.
There's something else Kate has no regrets about — her family's participation in the reality TV show that made them a household name.
"Honestly, 100 percent, the kids and I would both tell you it's a great experience," she said of their "Plus 8" days. "I do not regret anything in my life, and if I could rewind time, I would absolutely do the show again."
But those days are over, and now Kate has something else keeping her busy — promoting her new book, "Kate Gosselin's Love Is in the Mix," which features recipes, tips and tales for cooking for a big brood. It hits stores Tuesday.
