Sure, Courteney Cox's Dirt may have lost nearly a million viewers by its second episode, but that doesn't mean the show about a fictional tabloid magazine editor is completely off your radar, does it? There are still barely two million of you watching it, so at least twelve or two of you must care — especially when Rachel is coming!

And by that, we mean Jennifer Aniston, who agreed to help out her gal pal and come by the set to film a role for the show's March finale. Aniston will play Tina Harrod, editor at a rival magazine, whose masturbation scenes will be just as uncomfortable.
