Looks like we have more romance brewing behind the scenes of Gossip Girl!

A spy told W Magazine they caught the co-stars kissing at the DFW airport after spending T-day with Chace Crawford's family in Texas!

"Definitely on the lips," the source says of the kiss. "Not a French kiss, but a smooch definitely. They were being very flirty when people were not paying attention."

But doesn't Ed have a girlfriend? And wasn't she supposedly getting all cozy with Jason Lewis?

You know you love it.

XOXO
