You might want to think twice before stopping by Alexis Stewart's apartment uninvited: The daughter of domestic diva Martha Stewart has a permit to keep a loaded gun at home, according to the Post. Other notable locals with gun licenses include David Wright and Carlos Delgado of the Mets, Robert De Niro, billionaire supermarket mogul John Catsimatidis, and Donald Trump. (Two of Trump's sons, Eric and Donald Jr., also have licenses to keep firearms at home; Ivanka Trump's apartment is gun-free.) But it's Alexis, who recently launched a new TV series on the Fine Living channel, who may have the creepiest explanation for why she feels the need to keep a gun in a lockbox in her TriBeCa apartment: She keeps it in case an emergency forces her to abandon the city and she has to euthanize her elderly dogs. "They could never make it out of Manhattan. I could never leave my dogs to die of thirst in my apartment, so I looked on it as a euthanasia situation. I would never kill my pets unless they were going to die anyway."
