Tom and Katie Getting Death Threats?

Apparently the Cruises didn't have such a merry Christmas -- the Mail reports that Tom and Katie have been receiving death threats believed to be coming from some of the same groups who have been protesting the couple's involvement in Scientology.

According to the report, for security reasons Tom and Katie now live in separate residences (which might explain why we haven't seen them together for a while) and ride through the streets of New York in bomb-proof vehicles.

A sources tells the paper, "The threats are perceived to be so great that the FBI has been alerted. Tom is terrified. He doesn’t feel safe anywhere."
