Gwyneth Paltrow hit the Children of the City's Champions of Hope benefit gala last week in New York styling a black minidress with sparkly purple cutouts, black booties, and a glowing tan. It was a look meant to be seen and documented, and the actress-cum-guest of honor obligingly flashed her pearly whites as she posed for photographers at the charity event.

But was she smiling through gritted teeth?

So says Chuck Taylor, a former Billboard writer who posted a behind-the-scenes account of the shindig.

Paltrow, he claims, had little patience for the flashbulb frenzy her entrance ignited and was allegedly overheard sniping to her publicist, "I'm done. Get the roaches out of here."

Yikes. That doesn't sound like something an inner-aspect nourishing star like Gwyneth would say, especially when the shutterbugs were invited to the festivities to help promote a cause she supports.

But did she actually utter the insect insult? Not according to the guy supposedly on the receiving end of the ostensible lensmen put-down.

"Absolutely false," Paltrow's spokesman, Stephen Huvane, assures us. "Gwyneth absolutely respects the photographers at the events she attends."

But he freely admits that the Oscar winner, who has spent the last few months filming "Iron Man 2" in Los Angeles, doesn't have quite the same regard for the snappers who try to get candid shots of her when she's out and about with kids Apple, 5, and Moses, 3.

"However, the photographers-stalkerazzi who follow her and her children during the day -- she has, on occasion, called them some rather interesting names," quips the rep.

It's been a bit of a rough week for Paltrow. In addition to the roach rumor, Vanity Fair took a swipe at her GOOP lifestyle initiative with a spoof interview filled with advice that's slightly less helpful than, say, the three-week, pound-dropping detox she recently undertook after "a majorly fun and delicious 'relax and enjoy life phase' about a month ago."

Among the ersatz wisdom imparted by the mock Gwyneth is the quickest way to get one's leggings on: "My in-house leggings guru advises rubbing onto your legs a paste made from five spoonfuls of extra-virgin olive oil, turbinado sugar, and coarsely ground fair-trade coffee."
