Jon Gosselin, who’s currently facing a massive lawsuit from TLC, might be looking at even more trouble from his former hook-up, Kate Major.

As you may recall, back when times were good between Jon and Kate II, Jon convinced Kate to quit her job with Star Magazine by promising to hire her to work for him (to do what, we do not know).

According to Michael Lohan, Jon actually signed a handwritten note stating his intentions to hire Kate. He then backed out on the plan a few days later, and decided to go back to Hailey Glassman. Michael is now claiming that the note, though handwritten, was actually legally binding, which means Jon could be looking at a lawsuit from Kate in the near future.

Even if she doesn’t plan to sue, having Kate and Micheal pissed at him is probably not a good thing, since both of them have been called in to testify against Jon in his TLC trial, which is set to begin on December 14.
