TLC filed the lawsuit in October, claiming the Jon & Kate Plus 8 star violated his contract by making paid TV appearances and unauthorized public disclosures about the TLC show. The suit seeks unspecified compensatory damages from Gosselin and demands that the 32-year-old return money made from other TV appearances, as well as abide by the terms of his contract.
