Jon, Kate and their eight children have attracted a huge TV audience, screaming tabloid headlines and, now,a state labor investigation.

The Pennsylvania Department of Labor says it's looking into whether the hit reality show "Jon & Kate Plus 8" is complying with child labor laws.

The TLC series follows Jon and Kate Gosselin as they raise their eight young children, including 8-year-old twins and sextuplets who just turned 5. The show drew nearly 10 million viewers for its fifth-season premiere Monday following reports of trouble in the Gosselins' marriage.

Labor Department spokesman Justin Fleming tells The AssociatedPress that the department is looking into a complaint against the show.

TLC says it "fully complies" with state laws and regulations.
