To the surprise of very few, TLC filed a breach-of-contract lawsuit against Jon Gosselin on Friday morning, accusing the Jon and Kate Plus 8
star of violating his contract by making paid and unpaid TV appearances without the cable network's permission.
"The network has been trying privately and patiently for months to get Jon to honor the contract he signed and to comply with his obligations relating to public appearances and statements," reads a statement released by the network. "Those efforts have been unsuccessful."
Mark Heller, Jon's attorney, told PEOPLE Friday morning that he had yet to see the TLC legal documents, and later released a statement after "reading the alleged complaint on the Internet."
"Jon will vigorously defend against this baseless action, assuming Discovery and TLC choose to go forward with their claim by legally serving him with notice, and we are confident that through the course of litigation it will clearly be evident that Discovery and TLC exploited, manipulated and abused the Gosselins’ vulnerability and financial hardship," Heller's statement read.
Jon, 32, is in the midst of a bitter divorce
with his wife of 10 years, Kate
The suit was filed in Maryland's Circuit Court of Montgomery County, where TLC's parent company is based. A copy of the lawsuit was not immediately available, but it reportedly also alleges Jon harmed the show "with his constant criticisms" and revelations about what goes on behind the scenes on the show, says the Los Angeles Times
The suit wants Gosselin to abide by the terms of his agreement and return any money he made for other TV appearances.
