The men are traveling in a black Mercedes SUV and a white Escalade, and have appeared to be following Katie for the last couple of weeks, numerous sources have said.
As RadarOnline.com reported, Katie secretly rented a Big Apple apartment and moved into it with Suri just weeks before dropping her divorce bomb.
She filed in New York but as we've exclusively revealed, Tom plans to counter by filing in California and arguing the case should be heard there.
Many sources have suggested that Scientology will loom large in the divorce, especially how it plays into the way Tom and Katie raise their daughter Suri.
