What really happened that day at Jon & Kate Gosselin's Pennsylvania home, which had police breaking up a tiff between the parents?
Well, according to Star, it was the fact that Jon was canoodling with another woman -- and his twin girls freaked!
Star reports that 8-year-old Cara and Maddy called their mom after seeing their dad get "touchy-feely" with new babysitter, Stephanie Santoro.
Stephanie, of course, happens to be a "wannabe nude model" who Jon met at an airport bar!
When the kids called Kate she rushed over to the home, but Jon wouldn't let her in. The exes wound up in a heated argument and the cops were called.
Naturally, Star has found an old boyfriend of the babysitter who says Steph is "crazy."
"That girl is a danger to the kids. My message to Kate would be to not allow her children to be around her."
Really? Who isn't crazy in this situation?
