Courteney Cox did everything she could when she was here to promote FX's "Dirt" to suggest that her good friend "Jen" -- that would be Miss Aniston to you -- might be coming on the show.

And now, it appears, it's really going to happen.

According to FX, Aniston's set to appear in the March 27 finale of the show, in which Cox plays Lucy Spiller, the ruthless editor of a gossipy tabloid.

Perhaps Aniston will be playing someone letting the air out of Lucy's tires?
