Yesterday's story on celebrities and Fashion Week certainly incited some panic. And while some celebs will be paid to warm the front row - Welcome, Kate Bosworth! - the list of those who can't make it keeps growing. Witness Sean Combs, the stepfather of Zac Posen's label whose newest Sean John perfume launches with Estee Lauder during Fashion Week. Mr. Combs was supposed to have an incredible party on September 4 to unofficially kick off the week. But instead, he'll probably be at the Video Music Awards in Vegas, and his party's been rescheduled for the week after the Tents. Good news: Rumor has it, the bash will be even more opulent, more star-studded, and more fun than its Fashion Week replacement. Bad news: If Sienna makes it over to New York - and she may not, since the Twenty8Twelve shop launches in London that week - she won't have her favorite party buddy. But Sienna, we're totally available!
