Just another day in the life of Mrs. Tom Cruise!

After putting in a few quality hours at the Scientology Celebrity Centre in LA, Katie Holmes stopped by Jimmy Kimmel Live to promote her new TV miniseries.

Holmes plays Jackie Kennedy in the controversial 8-part series, The Kennedys, which premiered on ReelzChannel Sunday.

Reelz picked up the series after several major networks who refused to air it. The show's premiere and encore airing brought 1.9 million viewers to the channel -- the five-year-old network's highest numbers yet!
