During Halloween week, the American public was bombarded with several scary-ass images. There was Britney Spears in her Pepto-dipped tiger suit, Paris Hilton donning creepy cataract contacts and revealing her long-suspected inner demon, and of course the thought of Cupie doll Ashley Olsen riding (figuratively, at least) cyclist Lance Armstrong all over the Big Apple.

But perhaps the photo-opiest moment of the week was a determined looking Katie Holmes running the Nov. 4 ING New York City marathon in a FDNY hat (because her connection to New York's bravest has long been established) and a fuchsia tank top without a bra!

On this burning braless issue, running coach Tommy Owens confides to Us, "I would be concerned with her not having support." Minn's minions are also quite preoccupied with the fact that Mrs. Cruise (or, as she registered, "Katie Smith") began the race wearing lipstick and eye shadow, but quickly "sweated it off."

Life & Style finds an insider/hotel employee who says that while the world at large may have been astonished by Katie's historic run, she'd been training in Berlin on treadmills, and "sneaking out in workout clothes" to prepare.

Less than four hours after her five-and-a-half-hour run, Katie glammed it up in a black pants-y outfit and stepped out with Tom for a Lions for Lambs event at the Museum of Modern Art. While L&S, OK! and Star marvel at Kate's Herculean ability to wear heels that very night, In Touch finds the darker side.

A new tell-all-book about Tom Cruise by scandal-friendly biographer Andrew Morton will hit bookstores right around Oscar season, In Touch says. Apparently Katie is just heartbroken that the book will bring up all those nasty rumors about Tom's sexuality, cult-y Scientology, Suri's "real" dad, and that pesky "contract" to be Tom's girlfriend that 62 percent of readers believed she signed. They claim that these worries were what caused her to seem "distracted" at the Hollywood premiere of Lions on November 1. "She wasn't as talkative as usual," a friend/waitress reports. "It was a little odd."

I don't know, friend, maybe what was distracting her was the thought that in two days she'd be running 26.2 miles without a bra.
