The Associated Press is reporting that Jon and Kate Gosselin and TLC are currently being investigated by the Pennsylvania Department of Labor for violating child labor laws after receiving a complaint concerning the welfare of the Gosselin twins and sextuplets.

TLC released a statement in response to the investigation, insisting that they have been fully compliant with all labor laws. In the past, the network has claimed that Jon and Kate Plus 8 shoots only two days per week for no more than two hours per day.

After the show debuted this season to record numbers, TLC ordered 40 episodes of the show to be shot this year.
