While Hurricane Sandy wreaks havoc on New York City, its most famous denizens are tweeting and photographing the damage. Donnie Wahlberg posted a video of his apartment flooding that depicted a cereal bowl floating across his kitchen while the Blue Bloods star slogged through the mess. He later tweeted, "My entire building is under a foot of water. Awesome neighbors all banding together to help each other! Stay safe!" A short while later, he tweeted that he had reached higher ground: "Safe & Sound on Higher Ground! Don't worry about me. Material things are meaningless. Check in with those you know in the storm!" Alec Baldwin, who was seen out Monday morning walking his tiny dogs, tweeted that things had gone south quickly: "Possibly leaving our home to check into a hotel. #powerless No lights here, no Internet. My wife @hilariabaldwin and I, sitting in the dark wondering where is the storm? (No jokes please)." And if you were wondering about the Gosselin brood in Pennsylvania, they're fine. Kate Gosselin tweeted, "We are fine... From what I can see, lost one evergreen tree. That's it. I am NOT complaining...we are happy to be safe&warm! #luckyones."
