Heir to a real estate empire, J.P. is the reigning prince of Manhattan. But with his demanding princess keeping him on such a short leash, it'll be hard for J.P. to resist the new girl in town—especially once she starts walking the family dogs. Watch out J, with B in the picture, I'm smelling trouble. See how it started in Gossip Girl: The Carlyles.
