The French are coming to Gossip Girl.

In light of Blair's engagement to Prince Louis, we already know the latter's sister will arrive this fall and cause problems for our favorite Upper East Sider.

But TV Guide has now teased another impending foreigner, one who could be heating up the action in an unexpected way:

According to the latest Mega Buzz column in that publication, a "young, very attractive, French-speaking Catholic priest" will appear on the first two episodes of season five.

He'll presumably be around to marry Blair and Louis, but the magazine also says he "might find a certain bridesmaid with whom he'll, ahem, commune."

Oh, Serena. What trouble will you get yourself into next?!?
