Jon & Kate Plus 911!

Police were called to Jon and Kate Gosselin's $1.1 million home in Wernersville, Pa., Thursday after the reality stars got into a heated fight.

Kate arrived at the home (it was reportedly ex Jon's time to be with the kids) because she did not approve of the baby-sitter. Photographers on site claimed Kate was "locked out" of her house.

Around 6 p.m. Thursday, police arrived at the Gosselin family home in Wernersville, Pa., 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.

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?' "
