A slightly distracting 9 p.m. alarm went off at Thursday night’s Pisces party to celebrate the birthdays of Estée Lauder Group President John Demsey, CNN’s Alina Cho and modeling agent Marilyn Gauthier. Turns out it was society photographer Patrick McMullan’s phone. “That is my usual wake-up alarm,” he apologetically explained. “When everyone goes home from work, I go out to work.” Those toasting the trio and admiring Demsey’s art and photography collection at his Upper East Side town house included Kelly Rutherford, model Heidi Mount, Maurice DuBois, Robert Zimmerman, Rosanna Scotto, Jimmy Finkelstein, Pamela Gross, Kelly Bensimon and Marilyn Minter.
