No Gossip About Chace Crawford

Where in the world was Michelle Trachtenberg last night?

Not with Chace Crawford!

Trachtenberg and Crawford quickly shot down speculation that they’ve been getting cozy since she joined the cast of Gossip Girl.

At last night's event, when asked by New York magazine about the rumors, Trachtenberg said, "Tabloids make up crazy s--t."

And it was strictly a girls' night out for Trachtenberg last evening when she hit a VIP dinner at New York’s Macelleria restaurant for the Theory Icon Project followed by the opening of artist David Ellis’ “Flyaway” show at the nearby Theory store.

I’m told Trachtenberg spent most of her time hanging with publishing heiress and model Lydia Hearst (above) and the model daughters of rocker Keith Richards, Alexandra and Theodora.

Trachtenberg and Hearst left the party at about 10 pm. No word if they continued their partying elsewhere.

Also at the Ellis affair were Gina Gershon, Damon Dash, May Anderson and Bijou Phillips.
