Katie Holmes: At Home in New York City

Wearing a plaid shirt with flared jeans and chatting on her cellphone, Katie Holmes was spotted making her way to the Gerald Schoenfeld Theatre for a matinee performance of "All My Sons" in New York City on Saturday (October 25).

Meanwhile, there's talk that Katie, husband Tom Cruise and their daughter Suri may just make NYC their homefront, as an insider tells that they've been busily buying up real estate to make their Big Apple living arrangement more comfortable.

"Tom and Katie now keep 5 units in the building," a source told Page Six. "They turned one into Suri's playroom. One they use for a gym and 2 apartments are for staff."

The insider adds, "In the past couple of months they've bought up all these other apartments. They're all separate and on different floors. Tom is seen coming in and out all the time and he's really friendly to everyone he meets. But Katie just kind of keeps her head down. Everyone in the neighborhood is buzzing about it."
