Kate Gosselin Arrives In NYC With Her Eight Children

Kate Gosselin's Saturday business trip to New York City turned suddenly – and briefly – sour when photographers trying to take her picture were blocked by security guards outside a photo studio.

Earlier in the day, Gosselin and her eight children had checked into a midtown Manhattan hotel to prepare for a TLC photo shoot that afternoon, which also included the Duggar family and the stars of the network's reality show The Little Couple.

Sometime after 3 p.m., Kate and her kids left the hotel and were followed by a pack of photographers. But when the group arrived at the City Stage studio in the Chelsea neighborhood, security guards attempted to keep the photographers back using umbrellas, styrofoam boards and folding event tables, according to an eyewitness.

Kate's own security detail tried to keep the children out of harm's way and rushed them into the studio. "It must have been very upsetting for the kids," says one observer. Jon Gosselin was not seen during the disturbance.

Earlier in the day, he was spotted moving belongings, including a flat-screen TV, into his new apartment on Broadway.
