Hide your antidepressants and your carbs! The New York Marathon is this weekend, and according to OK, none other than Tom Cruise and Katie Holmes jumped on a plane last night so that Katie could live out her life's dream, which apparently consists of running in the cold, amid a big mob of sweaty, ropy-limbed people, while strangers yell at her from the sidelines. Hm. Actually, that's probably not so different from her everyday life. Katie's family is flying in from Ohio to "watch" her run through the five boroughs, we're told. Frankly, we would have told them to stay home, you can probably see it better on TV and in magazines next week, and speaking of that, does the world really need more pictures of Tom trying to bond with Katie's Catholic parents, flashing his giant white teeth and leaping at their legs like a little Jack Russell while they scowl and think about how he's going to hell? Honestly. Those give us total secondhand embarrassment.
