Ed Westwick and Jessica Szohr Cause ‘Gossip’

Spotted: Chuck Bass and Vanessa Abrams, canoodling in coach on a cross-country flight.

The New York Post is reporting that Gossip Girl co-stars Ed Westwick, 21, and Jessica Szohr, 23, were seen getting more than friendly at the Dallas airport.

“They were trying to be discreet by stealing kisses near the gate,” says the paper’s source.

The pair, whose onscreen characters briefly flirted in an early season-two episode, rode coach class. The source adds, “They were kissing in the aisles, but once they sat, she read her script and he drank a Heineken.”

Back in September, Westwick had been caught making out with Drew Barrymore, 33, in New York at a Saturday Night Live after-party.

In addition to his starring role on Gossip Girl, the Hertfordshire, England-born actor is the new face of a K-Swiss ad campaign.

On the series, Szohr’s character Vanessa is in a relationship with Chace Crawford’s “Nate Archibald.”
