Maryland's Circuit Court of Montgomery County has granted motions filed by the network's lawyers to depose Glassman, 22, Lindsay Lohan's dad Michael, 49, as well as Gosselin's lawyer Mark Heller, manager Michael Heller, bodyguard Thomas Meinelt and his talent rep Matthew Kirschner.
In October, TLC sued Gosselin, 32, for breach of contract, accusing the Jon & Kate Plus 8 star of making paid and unpaid television appearances without TLC's permission. At the time, Mark Heller called the action "baseless" and said the network "exploited, manipulated and abused the Gosselins' vulnerability and financial hardship."
Gosselin, of course, is in the middle of another legal matter – his divorce from Kate.
Lohan had publicly stated at one point that he and Gosselin were working on a reality show together about divorced dads.
