Katie Holmes rides the subway

Katie Holmes has cottoned onto the craze, jumping on the same bandwagon as Jessica Alba and Jay-Z, and even Rihanna who sampled the London Underground.

Katie Holmes was seen riding the New York subway on Wednesday, going incognito with her hair scraped back into a ponytail, opting to go make-up free beneath large sunglasses.

She also seemed to be prepping for winter, wearing a knitted cream sweater and dark blue jeans, carrying an oversized leather bag and the signature pose of a commuter – keeping her head buried

Using public transport is a stark change from her former life as a Cruise, when she relied not only on chauffeur-driven cars, but also on exclusive A-list travel methods of helicopter ferrying.

It’s almost as if Katie Holmes’ ride on the subway was a metaphorical two fingers up at ex-husband Tom Cruise.

On Tuesday, Katie Holmes was seen with daughter Suri, arriving home from school by foot instead of a lift from a personal driver.

The six-year-old started at the elite Avenues school in New York last month.
