Cops called to Jon and Kate Gosselin's home

(People.com) -- When Kate Gosselin appeared on Monday's "Today" show, she told host Meredith Vieira that she still loves her soon-to-be ex, "the Jon I knew." However, the stars of TLC's "Jon & Kate Plus 8" seem to have lost that loving feeling.

Around 6 p.m. Thursday, police arrived at the Gosselin family home in Wernersville, Pennsylvania, where the exes were engaged in a verbal argument. A source close to Kate Gosselin confirms she called police.

"[Police] got there and calmed the situation down," an officer tells PEOPLE. "No one was arrested and no citations were issued."

Another source says Kate called the house to find out which babysitter was helping with the children. When she didn't approve of the caretaker, an argument with Jon ensued.

"Due to the custody agreement, Kate couldn't enter the property," the source says. "The cops had no choice but to tell Kate she couldn't go past the gate."

Distraught and in tears, Kate left and checked in to a nearby hotel.

Tears are something Kate is getting used to: In this week's PEOPLE the now single mother says, "I cry all the time, in numerous airports, in airplanes."

She'd rather not have her emotional life be so public, but she says, "It's not like I can put the tears on hold. So I try to cry very incognito, behind my sunglasses. And after those tears, there's always the feeling of, 'how did I get here?' "
