You're not really a New Yorker until you're riding the subways. Ask Katie Holmes, who was spotted with her daughter Suri Cruise riding the train just like any other city-dweller on Saturday (Nov. 17).

One key difference, however, is that paparazzi isn't tailing anyone else, and nobody's taking pictures of that bum passed out in the corner of the R train.

She's been spotted on the train frequently of late, riding it to and from work as she stars in the Broadway play Dead Accounts.

Why Holmes is riding the train when she could easily take a cab or car service is beyond us, but one thing's for certain, she's definitely saving a few dollars on cab fare.
