N ow that Google has moved into its 300,000-square-foot kingdom on Eighth Avenue, founders Larry Page and Sergey Brin are putting down roots in town. Or at least one of them is: A source says that half of the power duo just bought an apartment in the tower section of 15 Central Park West. No word yet on which billionaire will be bunking near Denzel Washington and Jeff Gordon, both of whom reportedly snapped up apartments there, but he’s paying roughly as much as Sting did for the swanky $30 million penthouse he just purchased in the building. That apartment has 5,500 square feet, five bedrooms, and a terrace. The mystery Googler’s broker, Corcoran’s Patricia Warburg Cliff, declined to comment. Asked to confirm the purchase, a spokesperson for the Web’s go-to tool for snooping wrote, “It is not our practice to comment on the private lives of our employees.” A Google search came up empty.
