Wondering why your Women's Self-Defense class was so empty on Thursday night? Maybe everyone skipped out to attend a performance of the play Seven at Diane von Furstenberg's 14th Street studio. The multi-writer script is based on personal interviews with seven women in the Vital Voices Global Leadership Network who've overcome tragedy and hardship to become community pillars. In the audience were such self-empowered females as Peggy Siegal, Kim Cattrall, and Fran Lebowitz. "This is the second time I've seen it," said von Furstenberg at the dinner that followed. "And I just find it so moving." Lebowitz was also moved…to find a cigarette.

"Are you the smoking police?" she asked when we approached her mid-puff. After we assured her that we held no badge of any kind, the famously acerbic writer offered her thoughts on the sad state of feminism today. "We live in the richest country in the world, in 2008, and they will not elect a woman president here," she griped. "It is intensely annoying. I mean, really, I would like to be the president. I've never watched a State of the Union address without being filled with envy. It's my first pick for a gig. And I have a solution to every problem. So I'm available if Style.com would like to field a candidate."

Meanwhile, in midtown, Amanda Hearst and her pal Luigi Tadini hosted a fundraiser at the 57th Street Hearst Tower for Riverkeeper, a neighborhood eco-watch program that patrols the nation's waters. "Green can be fun!" insisted Tadini. But most guests, it seems, were already convinced. Exhaust-pumping town cars waiting outside were few and far between. In fact, a few PYTs admitted to having arrived via (gasp!) subway. For her part, Hearst was pleased that the family offices provided such great party digs. "You know what, I think I'll do a New Year's party here this year," she said as the evening drew to a close. Mark your calendars, people.
