New Gossip Girl star Michelle Trachtenberg is accused of being just that, after a blog post on Just Jared claims the actress talked smack about newly wedded Pete Wentz as she waited for a flight over the weekend.
When asked about the story by Ryan Seacrest on his KIIS-FM show, Michelle flatly denied ever speaking negatively about the Fall Out Boy frontman, who tied the knot with Ashlee Simpson on Saturday.

"Pete's been a friend of mine for years. I think the world of him. I would never trash him," said Michelle, adding that she's "very happy" for the couple.

Nevertheless, Ryan did pass on some sage advice: "If you're gonna talk crap on somebody, do it via text. That's how I roll."

Unless, of course, you're dissing Simon Cowell each week in front of 30 million American Idol viewers. Then it's OK to speak your mind freely and openly.
