A word to any would-be reality show stars: If you're going to bring your camera crew along with you, give people some advance warning. At a dinner at Bette last night that was hosted by Carlos de Souza, a certain Upper East Sider who was filming for a Bravo pilot turned up with a full complement of cameramen and soundmen. Turns out reality shows and press make for a hot-button issue when it comes to intimate soirées. "I can't believe she brought a camera in here," one editor exclaimed. "I was told this was a private party, and private means no cameras!" Or, as one irate guest noted, reality show filming should be listed on the top of an invitation if for no other reason than to let the ladies know what to wear—and how much makeup to put on.
