The lawsuit, filed Friday in Maryland, alleges that Gosselin hasn't met the obligations of his contract as an exclusive employee, has appeared on other programs for pay and made unauthorized disclosures about the show.
Gosselin has starred for two years in "Jon & Kate Plus 8," which has been consumed in recent months by marital turmoil as Gosselin and his wife, Kate, feuded, then filed for divorce. The couple are the parents of young twins and sextuplets.
Recently, TLC announced the show would be renamed "Kate Plus Eight," with a reduced presence by Jon Gosselin. A TLC spokeswoman, Laurie Goldberg, has said the show's longtime future remains in question.
