"On Thursday evening at 7:05 pm, officers from the Lower Heidelberg Township Police Department were dispatched to the Gosselin residence" in Wernersville, Pa., an officer said. "The situation was calmed down by the officers. There were no citations or arrests made."

The officer, who declined to give his name, said it was not clear who placed the call. But Jon's attorney, Mark Jay Heller, told TVGuide.com that Kate called the police after Jon denied her entry into the home. The couple's custody arrangement says Jon and Kate each have "exclusive privileges at the home where the children live" during their respective visitation periods, Heller said.

"Kate apparently showed up unannounced and uninvited," Heller said, adding that she also "expressed dissatisfaction" with Jon's babysitter, 23-year-old cocktail waitress Stephanie Santoro. "Shockingly, [Kate] called the local police."

The police did not take any action because they determined the incident was a civil matter, Heller said.

Kate left after the incident and checked into a hotel. TVGuide.com's calls to her lawyer were not immediately returned.

The Gosselins' children were unaware of the situation because they were being bathed by the babysitter at the time, Heller said. "Jon puts above all else the well-being and the welfare of his children," Heller said. "He was thankfully able to insulate his children from any conduct or any interaction or any viewing of the police that came."

Heller said he did not know why Kate showed up to the residence, given that she knew the terms of the parenting schedule, or why she called the police. He said her actions may be the result of the stress from the split.

"I hope and would think that she's a good mother and a good person, but people sometimes when they're under stress and strain don't conduct themselves, retrospectively, the way they would've preferred to. I'm sure in retrospect she regrets what she did," he said. "Thankfully everything was resolved. We're certainly hopeful that something like this will never reoccur."
