This recent photo from the Gossip Girl set appears to show stars Matthew Settle and Kelly Rutherford embracing Chris Riggi, who plays Scott, the mysterious love child of Lily and Rufus (who they do not know is still alive as of the end of Season 2).

That's about to change, however, based on this  ...

Is a family reunion in store on Gossip Girl?

While the plot line involving the mysterious love child Scott has already been developing for awhile, no one knows it! We don't know what to expect once his identity is revealed to the rest of the Gossip Girl characters we love. Should be very interesting.

Also spotted on set during this round of filming? The lovely Michelle Trachtenberg.
