France has officially been invaded by the cast of Gossip Girl. As of Monday morning, Leighton Meester and Blake Lively were seen filming, with respective mystery men no less!

The ladies looked wonderful, as usual and as expected.

As for the great Ed Westwick (Chuck Bass), he was spotted a little bit later, shooting scenes with guest star Clemence Poesy. Check out an entire gallery of thumbnails here.

Check out Blake and Leighton below. What do you suppose could be happening with Blair and Serena in the scenes they're filming? When and how will Chuck get into the mix?
